Lee Ludd: Added a section about becoming invisible when you have two monitors.

{{Help|BugFixes=*}}
{{wikify}}
If you are unable to see your avatar, it could be due to several reasons,
including your graphics card, drivers or internet connection. Here's some handy
steps to help diagnose the problem: 
 
Are you using two monitors? 
--------------------------- 
At least on some computers, if you have two monitors and you rebake your av's texture
when your SL window is not sitting in the primary (i.e. first) monitor, you will
turn transparent. If this happens, just move the window back to your primary monitor
and rebake again.
 
 
What graphics card am I using? 
--------------------------------- 
Click on the Help menu at the top of your screen, and select 'About Second
Life'. In the window that opens, your graphics card type and manufacturer are
listed about half way down. 
 
Second Life supports medium to higher end nVidia and ATI cards. Support for
Intel graphics (which is a chipset on the motherboard designed primarily for 2D
graphics) is not available. 
 
 
Am I using the latest graphic card drivers? 
---------------------------------------------- 
Even brand new PC's often ship with outdated graphics card drivers. It is highly
recommended you go to the site for your graphics card and download and install
the latest graphic card drivers. 
 
ATI cards: www.ati.com 
nVidia based bards: www.nvidia.com 
 
 
I've done all that, and I am still blank! 
----------------------------------------- 
Open up preferences (ctrl-p) and click on the following tabs: 
 
Graphics Tab: 
* Change 'Draw Distance' from 128 down to 96, and click 'apply' 
 
Graphics Detail Tab: 
* Locate 'Avatar Vertex Program' under the shaders section and UNcheck it -
click apply 
if it is unavailable it means your graphics card does not support it 
 
* Make sure the 'avatar mesh detail' slider down the bottom is in the middle
setting. 
 
Adv. Graphics Tab: 
* Disable AGP graphics (if selected) by unchecking it. 
* Increase Graphics Memory to the maximum available (if not already selected) 
* Click Apply 
 
Network Tab: 
* Maximum Bandwidth - this setting should be changed to a speed lower than your
internet connection speed. 
Suggestions: 768 Kb Internet speed, set to 400 kbps 
1MB/s Internet speed, set to 500 kbps 
1.5MB/s or greater, set to 1000 kbps 
 
* Increase Disk Cache size to the maximum (1000 MB) 
* Click Apply 
* Still under the Network tab, click the 'Clear Cache' button. then click OK 
 
Log out of Second Life. Log back in 
 
 
Whew! That worked! Thanks a lot! 
-------------------------------------- 
You're welcome :) 
 
 
No, all that didn't help!!! What now? 
--------------------------------------- 
It's possible your firewall may be preventing transfer of some data - try
disabling your firewall temporarily and relogging in to Second Life. Should that
not assist, please contact our tech support department via support@secondlife.
listing your system specifications, and the steps you have tried (as above) to
correct the issue.

Lee Ludd: Advice to use very negative channel for inter-object communication.

{{LSL_Function
|func_id=23
|func_sleep=0.0
|func_energy=10.0
|func=llSay
|sort=Say
|p1_type=integer
|p1_name=channel
|p2_type=string
|p2_name=msg
|func_desc=Says the text supplied in string ''msg'' on channel supplied in integer ''channel''.
|return_text
|spec
|caveats=Text can only be a maximum of 1024 bytes. Phrases spoken with llSay can only be heard within 20 meters of the speaking object. An object can '''not''' hear itself, to prevent problems with recursion.
|examples=<lsl>
default {
state_entry()
{
llSay(0,"This is an incredibly useless program." );
}
}
</lsl>

|also_functions=*{{LSLG|llWhisper}}
*{{LSLG|llOwnerSay}}
*{{LSLG|llShout}}
*{{LSLG|llInstantMessage}}
|also
|notes=If one object 'says' something to another object (e.g., a button that, when touched,
turns on a lamp), it is a good idea to use a very negative channel, e.g.,
<lsl>
llSay(-5243212,"turn on");
</lsl>
It is impossible for an avatar to chat on a negative channel, and extremely unlikely that some
other object would accidently say something on such a channel. (Of course, the intended target
of the message must be set to 'listen' on this channel.)
