Dante Tucker:

This page servers to explain some of the first questions most emerald users ask when finding IRC in the client.

== IRC in Emerald ==

IRC is a chat system older then the internet itself (not really). IRC has been integrated into the client to replace LL's failing group chat system. Unlike group chat IRC is stable, fast and won't fail when SL is acting shitty.

You can create arbitrary channels that others can join to chat in.

== Using it ==

=== Joining IRC ===

In the IRC tab clicking "New" will bring up a window with a few options.
*Nick: This is the nickname you want.
*Server: This is the address and port the IRC server you want to connect to is running on. The default is run by the Emerald crew and is free for all to use.
*Password: This is the password needed to connect to the server. Usually this is blank.
*Channel: This is the channel on the server you want to chat in. Entering a non-existant one will create it with you as the owner.
*Settings Tag: This is the name your settings will appear as in the IRC tab.

=== Common commands ===
Nickname commands:
* /nick <the nickname you want>: Will change your nickname
* /msg nickserv: nickserv provides nickname services, type "/msg nickserv help" for more info.
**/msg nickserv register <password> <email>: This registers your nickname with chosen password and email.
**/msg nickserv identify <password>: identifies you, needed when logging on with a protected nickname.
Channel commands:
*TODO: For now type "/msg chanserv help"

I could use some help with this page, many of these items are obscure and known only to elite hackers and Linden programmers :-) [[User:DanielRavenNest Noe|DanielRavenNest Noe]] 22:05, 20 August 2009 (UTC)

:I added some more options where I were sure what they did and sent a mail to the [[SLDev|SLDev mailing list]]. Let's cross fingers that some of them jump in :-) Otherwise, it might be good to poke [[User:Rand Linden|Rand Linden]] on this. He seems to be the right one.

Why does this page exist? It's only point for existence is inclusion in the Glossary, however it is not a SL specific term anymore then the word "car" is.
Not to mention how tiny it is in it's current state. [[User:Dante Tucker|Dante Tucker]] 21:50, 28 June 2009 (UTC)

:I agree that the version provided wasn't very helpful for anyone. I took the remark as a motivation to [https://wiki.secondlife.com/w/index.php?title=Collar&diff=416113&oldid=83661 rewrite the article]. I hope this version fits the cretaria for a SL wiki article and nullifies the request for deletion.

God Mode

2009-08-21T00:23:55Z

Dante Tucker: Grammar fix

{{Help|Glossary=*}}

"God Mode" is the term used to describe the enabling of administrative tools and features in the Second Life Viewer.

Although the features and menus are compiled into the viewer, if an unauthorized user attempts to enable "God Mode" via {{KeyCombo|ctrl=*|alt=*|G}}, or the ''Advanced > Request Admin Powers'' menu option, a dialog is displayed informing the user that "'''Request for special powers failed. This request has been logged'''". The options available to an authorized user can still be viewed via {{KeyCombo|ctrl=*|alt=*|V}} or the ''Advanced > View Admin Options'' menu option- although "God Mode" appears to be enabled, the server will not act upon any attempts to use them.

== What it can do? ==

In Linden-owned grids (such as [[Agni]]), "God Mode" enables [[:Category:Linden Lab Employees|Linden Lab employees]] to perform tasks entirely in the viewer, such as:
* edit land or region info
* kick or freeze avatars,
* claim land or objects to themselves
* Log everyone out of Second Life

"God Mode" also allows parcel restrictions such as "no fly" to be ignored.

== What do they use it for? ==

Linden Lab employees may use "God Mode" for many reasons, including the privacy granted from being invisible to sensors{{footnote|Lindens in God Mode are only hidden from sensors, in case the sensor is in the same [[region]] as the Linden. See [[User talk:Soft Linden#sensor caveat]].}}, reclaiming abandoned land and dealing with griefers.

== God Mode Levels ==
The [http://svn.secondlife.com/trac/linden/browser/trunk/indra/llcommon/indra_constants.h#L242 Viewer source code] shows that there are several levels of "God Mode" (each level has all the previous levels' powers):

=== GOD_NOT ===
Value: 0
Presumably the default "God Mode" status given to every logged-in user

=== GOD_LIKE ===
Value: 1
* rename objects without modify permission

=== GOD_CUSTOMER_SERVICE ===
Value: 100
* Toggle character geometry
* Take copy
* Owner To Me
* Set To Linden Content
* Claim Public Land

=== GOD_LIAISON ===
Value: 150
* Enable land auction

=== GOD_FULL ===
Value: 200
Difference from [[#GOD_LIAISON|GOD_LIAISON]] not apparent.

=== GOD_MAINTENANCE ===
Value: 250
Difference from [[#GOD_FULL|GOD_FULL]] not apparent.

Advanced menu/1.23/1.23

Dante Tucker: Information on many options.

{|style="float: right;"
|{{GettingStartedNav}}
|-
|<center>__TOC__</center>
|}

This page is part of the Second Life User's Manual, describing how the Viewer software works. Please see the main [[User's Manual]] page as a starting point.

The Advanced Menu contains many technical displays and functions not needed for new or basic Second Life users. It is primarily aimed at specialized uses and debugging the software. A few of the most useful items for general users are noted below.

By default, the Second Life Viewer's Advanced menu is not visible. To display it:

* '''PC''' - {{KeyCombo|ctrl=*|alt=*|D}}
* '''Mac''' - {{KeyCombo|ctrl=*|opt=*|D}}

On some operating systems, this shortcut is already taken by another application, so you will need to hold down {{KeyCombo|ctrl=*|alt=*|shift=*|D}} instead.

Click the video player below to learn how to activate the menu and [http://support.secondlife.com/ics/support/default.asp?deptID=4417&task=knowledge&questionID=4338 learn more in our Knowledge Base]:

Find more information about specific menu items below, and in the [[:Category:Advanced menu]] wiki page.

<videoflash>IrndvDk-pzY</videoflash>

=== Useful Items for General Users ===

* '''High Res Snapshot''' - doubles pixel size of snapshots saved to disk

* '''Character > Character Tests > Go Away/AFK When Idle''' - disables inactivity timers for showing (Away) (5 minutes), and auto-logout (30 minutes)

* '''Character > Rebake Textures''' - Forces your computer to redo and send your avatar skin + clothing again. Sometimes this does not happen correctly the first time, and other users will see your avatar as a persistent cloud (avatar did not load at all), grey (shape loaded but not textures), or parts look wrong (some textures did not load properly).

* '''Debug Settings''' - Enter "RenderFarClip" to set draw distance to non-standard values. Values below normal 64m minimum are useful to reduce lag. '''Caution:''' randomly messing with debug settings can totally mess up your viewer program.

=== All Advanced Menu Items ===

In the section COMMON CAUSES OF INVENTORY LOSS >> Land owned by a Resident, it states that Land Owners can delete other persons objects on there land. This is not true. The "Delete" option is pickable, however it actually just returns the object when chosen.

This page is an easy reference to common queries about '''Second Life limits'''. Some of these will almost definitely change over time, so if you spot something incorrect/outdated, please take a moment to update it. Also see the [http://support.secondlife.com/ics/support/default.asp?deptID=4417&task=knowledge&questionID=5480 Knowledge Base counterpart of this article].

== Building ==
* '''Max. prim dimensions (non-megaprim)''' - 10x10x10 m
* '''Min. prim dimensions''' - 0.01x0.01x0.01 m
* '''Max. # of prims in a linkset''' - 255
* '''Max. link distance''' - See [[Linkability Rules]].
* '''Max. # of prims in a physical object''' - 32
** If you try to link more, it'll either say "Can't enable physics for objects with more than 32 primitives" or "Object has too many primitives -- its dynamics have been disabled.".
** Note that this limit includes the driver and passengers of physics-enabled vehicles, e.g. if you are making a car to sit 4 people, 28 prims are available for the car itself.
* '''Max. build height''' - 4,096 m (SL 1.20.x or later required)
** This is 768 m for viewers prior to SL 1.20.x
* '''Max. prim name length''' - 63 bytes UTF8 [[string]]
* '''Max. prim description length''' - 127 bytes UTF8 [[string]]

== Avatar ==
* '''Max. # of attachment points''' - 30 for avatar, 8 for HUD.
** They can be viewed in Edit menu > Detach Object.
* '''Max. unassisted fly height''' - Stable hover almost 150 m above the ground (terrain mesh).
** While an improvement over the previous limit of 50 m, Torley thinks this limit is ridiculous because Second Life is 3D. You can easily acquire a flight attachment to fly up to seemingly infinite heights.
* '''Common shoe sizes''' - Most women's shoes are designed for a size 0 (zero) foot. Men's generally scale up to 14. You can check this by going to Edit menu > Appearance and clicking on the Shape > Legs tab.
* '''Max. length of avatar name''' - 31 for first name, 31 for last name, 63 for total (including the space).

== Chat (text) ==
* '''Whisper distance (done via scripting objects)''' - 10 m
* '''Chat distance''' - 20 m
* '''Shout distance''' - 100 m
** Rule of thumb: when you're at default zoom (View menu > Reset View), if you can see another other person's nametag, they can see your chat. If they're far enough away that you don't see a nametag, they won't "hear" you unless you shout.
* '''Max. length of a chat message''' - 1023 bytes/single-byte characters
** The same holds true for an IM<->email replies.

== Profile ==
*'''2nd Life tab's About field''' - 500 characters
*'''Picks tab''' - 10 picks with 1023 characters each
*'''1st Life tab's Info field''' - 250 characters
*'''My Notes''' - 1022 characters

== Groups ==
* '''Max. # of groups you can belong to''' - 25
** Roles within groups are sort of like sub-groups. In many cases, you can use them instead of creating new groups.
* '''Min. # of members in a group''' - 2
** A group with only 1 person for 48 hours will be disbanded (cancelled).
* '''Max. # of roles allowed in a group''' - 10 (including "Owners" and "Everyone", which can't be deleted)

== Inventory ==
* '''Max. # of inventory items that can be sent in a folder''' - 42
** Folders count as items too. This has more to do with packet size limits than cheeky Douglas Adams references. ;)
* '''Max. notecard size''' - 65,536 bytes

== Land ==
* '''Max. parcel size''' - 65,536 m2
** Covering a whole region, or square on the World Map.
* '''Min. parcel size''' - 16 m2
* '''Max. "NO ENTRY" ban line height''' - 768 m above the terrain mesh.
** This is if you're explicitly banned from a parcel. If the parcel is simply not public access or restricted to certain Residents/a group, then the access lines go up to 50 m above the terrain mesh.
* '''Max. prims in a region''' - 15,000 (3,750 prims for an [http://support.secondlife.com/ics/support/default.asp?deptID=4417&task=knowledge&questionID=4235 Openspace] region) <== (July 6, 2008) This limit for openspace sims is an intended limit, however due to a bug in the object bonus option the limit is currently unlimited. Using more than 3750prim on an openspace is still unadvisable because the sim performance decreases rapidly with the extra prims. Some openspace sims have been reported to hold 18000+ prims momentarily before crashing.
* '''Max. Autoreturn value''' - besides "0" (which means: ''never''), 999,999 minutes is the biggest autoreturn value.
* '''Terraforming limits''' - Almost all mainland can be raised/lowered by +/-4 m. Estate (private island) terraformability is settable to a max of +/-100 m by the estate owner or managers. Bay City regions cannot be terraformed, and there may be others.--[[User:Shadoe Landman|Shadoe Landman]] 13:07, 6 July 2008 (PDT)
** A few, very old regions like Da Boom have a terraform range of +/-40 m.
* '''Max. water height''' - 100 m
** Region water height is usually 20 m, and adjacent regions should have the same water height, or else they'll look discontinuous.
* '''Misc. estate limits''' - You can have a max. of 10 estate managers, 500 allowed Residents, 63 allowed groups, and 500 banned Residents.
** See World menu > Region/Estate > Estate tab.
* '''Mainland max. # of agents''' - 40 avatars/region
* '''Island max. # of agents''' - 100 avatars/region
* '''Freeze Time''' - Land owners can [[freeze]] other Residents for up to 30 seconds.

== Performance ==
* '''Healthy Viewer FPS''' - Generally, FPS above 15 is good. The higher it gets, the smoother. You can check via Help menu > Lag Meter, or for more advanced usage, see View menu > Statistics Bar.
* '''Avatar Rendering Cost scores''' - [http://blog.secondlife.com/2008/05/01/who-me-yes-you-couldnt-be-then-who-introducing-avatar-rendering-cost/ Learn all about it!]

== Scripting ==
For specific scripting limits, lookup calls in the [[LSL Portal]].

== Textures ==
* '''Aspect ratios''' of profile, place, etc. pictures — all of these were measured at UI size = 1.000:
** '''Search > All for "Classifieds", "People", and "Places"''' - 4:3 (256x192 pixels)
** '''Search > Places and Classified tabs''' - ~7:5 (398x282 pixels)
** '''Search > Land tab''' - ~7:5 (358x252 pixels)
** '''Profile > 2nd Life tab''' - ~4:3 (178x133 pixels)
** '''Profile > Picks tab''' - ~16:9 (288x162 pixels)
** '''Profile > 1st Life tab''' - 1:1 (133x133 pixels)
** '''Profile > Classifieds tab''' - ~3:2 (206x137 pixels)
** '''Profile > Web tab''' - 1:1 (400x400 pixels) Note Scrollbars will eat 15 pixels
** '''About Land > Options tab''' - ~3:2 (178x117 pixels)
** '''Group Information > General tab's "Group Insignia"''' - 1:1 (126x126 pixels)
*** Some of these textures are shared (for example, Search > All place pages, Search > Places, and About Land > Options use the same image), so you should pick a well-balanced ratio and size.

* '''Maximum texture size''' - 1024x1024 pixels
** We strongly recommend you use as small textures as possible because larger ones consume more memory and take substantially longer to load. See also [[Avatar Rendering Cost]].

== Misc ==
*'''[http://secondlife.com/currency/describe-limits.php Billing and Trading Limits]''' - Look at the linked page for [http://secondlife.com/whatis/economy-market.php LindeX] currency exchange limits.
*'''Contacts in Communication > Friends tab ''' - A maximum of 20 simultaneous contacts can be selected to change permissions, remove, or invite for a conference chat.

*'''Picks tab''' - 10 picks with 1023 characters each
*'''1st Life tab's Info field''' - 250 characters
*'''My Notes''' - 1022 characters

== Groups ==
* '''Max. # of groups you can belong to''' - 25
** Roles within groups are sort of like sub-groups. In many cases, you can use them instead of creating new groups.
* '''Min. # of members in a group''' - 2
** A group with only 1 person for 48 hours will be disbanded (cancelled).
* '''Max. # of roles allowed in a group''' - 10 (including "Owners" and "Everyone", which can't be deleted)

== Inventory ==
* '''Max. # of inventory items that can be sent in a folder''' - 42
** Folders count as items too. This has more to do with packet size limits than cheeky Douglas Adams references. ;)
* '''Max. notecard size''' - 65,536 bytes

== Land ==
* '''Max. parcel size''' - 65,536 m2
** Covering a whole region, or square on the World Map.
* '''Min. parcel size''' - 16 m2
* '''Max. "NO ENTRY" ban line height''' - 768 m above the terrain mesh.
** This is if you're explicitly banned from a parcel. If the parcel is simply not public access or restricted to certain Residents/a group, then the access lines go up to 50 m above the terrain mesh.
* '''Max. prims in a region''' - 15,000 (3,750 prims for an [http://support.secondlife.com/ics/support/default.asp?deptID=4417&task=knowledge&questionID=4235 Openspace] region) <== (July 6, 2008) This limit for openspace sims is an intended limit, however due to a bug in the object bonus option the limit is currently unlimited. Using more than 3750prim on an openspace is still unadvisable because the sim performance decreases rapidly with the extra prims. Some openspace sims have been reported to hold 18000+ prims momentarily before crashing.
* '''Max. Autoreturn value''' - besides "0" (which means: ''never''), 999,999 minutes is the biggest autoreturn value.
* '''Terraforming limits''' - Almost all mainland can be raised/lowered by +/-4 m. Estate (private island) terraformability is settable to a max of +/-100 m by the estate owner or managers. Bay City regions cannot be terraformed, and there may be others.--[[User:Shadoe Landman|Shadoe Landman]] 13:07, 6 July 2008 (PDT)
** A few, very old regions like Da Boom have a terraform range of +/-40 m.
* '''Max. water height''' - 100 m
** Region water height is usually 20 m, and adjacent regions should have the same water height, or else they'll look discontinuous.
* '''Misc. estate limits''' - You can have a max. of 10 estate managers, 500 allowed Residents, 63 allowed groups, and 500 banned Residents.
** See World menu > Region/Estate > Estate tab.

** '''Group Information > General tab's "Group Insignia"''' - 1:1 (126x126 pixels)
*** Some of these textures are shared (for example, Search > All place pages, Search > Places, and About Land > Options use the same image), so you should pick a well-balanced ratio and size.

* '''Maximum texture size''' - 1024x1024 pixels
** We strongly recommend you use as small textures as possible because larger ones consume more memory and take substantially longer to load. See also [[Avatar Rendering Cost]].

Each prim is represented by a set of parameters, including position, scale, rotation, shape, cut, hollow, etc. Prims can be linked together into link sets. They can also be attached to avatars, but this process is separate from linking. Primitives are implemented in LLPrimitive, with vertex generation performed in LLVolume and rendering in LLVOVolume.

==== Profile ====
A profile is used to display various information about a resident in the profile window. A profile will always contain the resident's name, "born" date, account type and partner. Other information can be left blank by the resident.

==== Quaternion ====
Representation of a rotation. SL uses unit quaternions represented in four floats. This allows only three floats to be transmitted and the remaining value reconstructed on the viewer.

==== Ruth ====
This is the name given to the Second Life default avatar. When a simulator renders your avatar initially, it is sometimes unable to acquire all the information on your mesh, clothing, textures. In extreme cases, the sim has to render you with no info whatsoever, so it has a default, a female figure dubbed "Ruth". SL residents typically refer to logging in and appearing as the default as "being Ruthed". In viewer release 1.20 and following the default avatar becomes instead a glowing white particle cloud ("lumorphous blob").

==== Scripted Object ====

==== Skin ====
A texture image that replaces the default skin of your avatar. Cannot (usually) be adjusted by the appearance sliders, but looks much better than the default skin.

In 1.20 and later, skin can also refer to the theme your viewer is using. As of 1.20 the themes include Default (the grey and purple classic look of the viewer) and Silver (a lighter, blue look formerly known by the internal code name Dazzle).

==== Sim ====
Short for simulator. In common usage, a Second Life region, a square of land 256x256 meters. "Sim" may also refer to the server host machine, for example sim1234.agni.lindenlab.com. The SL server grid consists of over 5000 servers. Each server hosts several simulator processes (regions, or "sims"), of which there are over 22,000 (as of July 2008).

==== Simulator ====
The primary SL server process. Each simulator process simulates one 256×256 meter region. As the viewer moves through the world it is handled off from one simulator to another. Multiple simulator processes run on each server host, currently 2 to 16.

==== Snapshot ====
A button in the UI that will open up the snapshot preview window (Ctrl-Shift-S) with a screenshot of your current view ( ` will save the snapshot directly to your hard drive).

==== Slebrity ====
Slebrity is a portmanteau of SL for Second Life and celebrity. It refers to an avatar who has become notable in second life media, though not necessarily in the wider world.

==== Spam ====
An unsolicited instant message, notecard, texture, group invite, animate request, or object sent to multiple people. This can be sent by another player, or by an object containing a script.

Viewer Memory Manager

2008-07-14T00:51:46Z

Dante Tucker: more grammar edits.

[[Category:Linden Lab Projects]]

= Summary =
Currently the Second Life Viewer uses default memory allocators on OSX and Linux, and SmartHeap on Windows. None of these solutions provide run time memory profiling. When last investigated, Windows saw approximately a 15% overall framerate improvement when using SmartHeap. We need to find a cross platform solution that preserves as much of this performance optimization as possible while providing hooks for run time memory profiling.
= Objectives =
* Replace SmartHeap on Windows with a memory allocation library that is cross-platform and open source
** It needs to allow us to track memory allocations at run time. This could be a command line option if there is a performance overhead, but the overhead needs to be low enough to continue to run real time.
** Performance must remain comparable to SmartHeap on Windows
** The ability to dump a detailed memory profile would enable residents to submit memory leak / bloat information to Linden Lab and the OS community

SLDEV Discussion - Texture Cache Plan of Attack

2008-06-15T01:28:13Z

Dante Tucker: Minor typo.

{{ViewerArchNav|parent=Image System}}

Discussion is underway in the SLDev Mailing List regarding options to overhaul the texture cache. Mostly the plan involves storing decompressed textures, rather than the JPG2000 compressed versions, which allows the Texture Fetch operations to skip the decode, which is currently the major bottleneck in the cache system. This article is for summarizing, planning, and status of this project. Please discuss via the SLDev mailing list.

== Overview ==
=== Current Implementation ===
Currently, the client will download uncached JPG2000 textures from the region/asset servers, progressively decode and apply them to the faces rendered in whatever quality level is currently available. As more data is downloaded, it is further decoded, and the quality rendered goes up. Textures are cached in a three-part system sharing space with the [[VFS]], described in the [[Texture Cache]] article.

=== New Plan ===
The discussion on the SLDev list has been very helpful in nailing down ways to improve the cache. The biggest change will be caching of textures in an un-compressed format - TGA or Raw - while preserving the existing obfuscation technique to prevent direct ripping of the cached images. In addition, the cache settings will be split into two separate caches - the VFS for objects that use it currently, and a completely new layer of cache exclusively for textures.

== Steps ==
=== Rework Cache to store multiple formats ===
Currently, the texture cache can read TGA and JPG2000 files from the cache. However, it has no way to ''write'' TGA to the cache. The interface between llTextureFetch and llTextureCache will need to be refactored to support storing and retrieving in a format-agnostic way, allowing JPG2000, TGA, and Raw to exist simultaneously in the cache, with the possibility of adding others down the line if needed relatively easily.

In short, the calls from llTextureFetch to llTextureCache, and the return data, should include a Format Identifier, a block of data for the image itself (in whatever format is indicated by the Format Identifier), and any other details that may be required such as data size, image dimensions, and (if necessary) color depth. llTexureCache should be able to store and retrieve this data in a format-agnostic way, ideally returning decoded data to llTextureFetch as a llRawImage object. Metadata would be stored in the cache index, discussed below, with the bulk of the data stored in the manner it is done now - subfolders with filenames equivalent to the UUID of the texture.

=== Rework Cache Index for Greater Storage ===
Currently, the Texture Cache shares space with the VFS, and is limited to 800MB - 80% of the maximum total "cache size", the other 20% of which is reserved for the VFS. With the cache capable of storing uncompressed files, it could grow much faster; and with the cost of disk space these days, limiting the cache to 1GB is ludicrously inadequate. A separate slider in the "Network" preferences tab should allow the individual specification of max VFS ("Object Cache") and max Texture caches. In discussion, many commenters stated that they would allocate as much as 100GB to a texture cache. Aside from the speed benefit garnered from a larger cache, it also will dramatically reduce the amount of textures that would need to be re-downloaded due to a lower cache discard rate.

The Cache Index would store Metadata about the texture - the Format ID, the dimensions, file size, and color depth (if necessary), and, like the current cache index, would also have the first (arbitrary number of) bytes of the actual data - primarily for obfuscation purposes, to prevent the casual ripping of textures from the cache. Multiple copies of the same texture could be stored in the cache, in different formats - for example, stored as JPG2000 while progressively downloading, then stored in uncompressed format once complete. The Texture Fetcher would simply request a texture, and the cache would respond with the cached version available with the lowest CPU-overhead - Raw first, then TGA, then JPG2000, with the network fetch as the fail-through option. Ideally, once a texture has been downloaded completely and decoded, it would be stored as a Raw image, and the JPG2000 version would be marked as "expired" or otherwise scheduled for purging from the cache. The bulk of the texture data, stored in the UUID-named file in the subfolders of the cache, will need to have an extension added to it that signifies the Format ID to allow co-existence of multiple encodings of the same texture.

Some discussion was brought up about XORing the raw texture data with a hard-coded key, or perhaps one based on the Hardware Hash of each individual machine - in effect a fast but low-quality encryption. This has been largely disregarded in the interest of attaining the best speed - although it remains an option if the community demands more obfuscation than currently exists in the texture cache.

=== Cache Discard Optimization ===
There is discussion on the [[Texture Cache]] page regarding further optimization or replacement of the Cache Discard algorithms, which should probably be moved here - however, this portion is not a part of the current ongoing discussion in SLDev. I will leave it to someone else to take the initiative on this.

Can anyone say if this test grid is like the beta? Do money events count as actual?

This grid does not seem to be functional anymore.

Voice

2007-05-07T17:37:42Z

Dante Tucker: add other main group, needs details

'''Voice''' is a feature that made its debut on its own grid and beta viewer in March of 2007[http://news.cnet.co.uk/gamesgear/0,39029682,49289943,00.htm].

==Recent developments==

It was recently (May 2007) rolled in to the main beta grid, and Linden Labs has put out May 15 as the day that the main viewer with voice will be completed. Whether this means that voice will be added to the main grid is unclear.

==System-wide Rollout==

Voice will be available free for landowners during the beta. Owners of mainland and island properties will be able to use the new feature for free[http://news.cnet.co.uk/gamesgear/0,39029682,49288048,00.htm].
However, owners of older islands who pay fees lower than the current $US295 per month may have to upgrade to be able to use voice.

==Controversy==

While many believe that voice in SL will be beneficial, some users are against the addition of voice to the main grid.

==Groups==

The [[Voice Mentors|Voice Mentors group]] is the main advocacy and help group for users having problems adjusting to the new system.
