Introduction
Second Life® is a virtual world filled with thousands of 3D places to explore that combines social interaction and 3D graphics in a unique way.
It features a huge amount of user-created content (270 TeraBytes), a convertible currency, and 750,000 active users doing almost everything imaginable.
What you need
Interacting with the Second Life virtual world requires the following:
(1) A Second Life account
(2) A Broadband Internet connection
(3) A computer capable of running the Viewer program.
(4) The Viewer program installed on your computer.
(5) Web browser to access the Second Life website, which is necessary to use some features.
Optionally you may use:
(6) A microphone for voice interaction
(7) Joystick or 3D mouse as a control device
Basic Concepts
Since Second Life is not like any other 3D environment, some basic concepts paticular to it are reviewed in this section. More words are defined in the Glossary.
The Grid - A set of servers hosting connected map regions plus supporting databases and networking. Together they make it possible for a user to log in, see, and interact with the 3D world. The main SL grid is called agni.
Map Region - Each server on the agni.secondlife.com domain runs several copies of a "Simulator" program, each of which represents one 256x256 meter area of the grid. When you move from one region to another, you are handed off from one server to another, giving the impression of a large 3D world. Currently the main (Agni) grid has about 29,000 map regions.
Technically a map region is a set of data, like a document, or spreadsheet, which can be saved, and reloaded if a server stops running. The Simulator program is constantly updating the data in real time, as users come and go, objects are added and removed, scripts running within the objects do things, etc. Map regions are also called 'sims' after the program that runs them.
Viewer - The program that runs on your computer that connects via the internet to the Second Life servers. It allows you to log in to the grid and then see and interact with objects and avatars around your current "location" in the virtual world.
Resident - An account that most Second Life users have, with a first and last name, profile, account balance, inventory, etc.
Avatar - The character that represents a resident when logged into Second Life, and appears on the 3D view area. Avatars are highly customizable.
Linden Lab - The company that owns Second Life.
Linden - Staff member of Linden Lab. Their accounts/avatars have the last name "Linden". For example, "Philip Linden" is the avatar used by Philip Rosedale, founder and Chairman of Linden Lab.
User-Created Content - Linden Lab codes the software and hosts the servers that runs Second Life. But most of the items you see when you are logged in are actually created by other users, such as clothes, furniture, weapons, animations, sounds, etc.
The Viewer
The Viewer provides a 3D interactive view, and additional menus, buttons, and windows to perform various functions. It uses your graphics card or chip to generate the 3D view that you see in real time. The data to produce the 3D view has to be downloaded from the servers as you need it for two reasons: First, the total data for the main grid is over 100 Terabytes, and second, it changes constantly. This is different than most online games, where the data is provided mostly on an installation disk.
As you travel from place to place, the servers send you data for an area around your current location out to a maximum 'draw distance' you have set. Within that distance, there will be an initial fast download of the area around you so you can see it, then slower updates as things change: other avatars come and go, and objects move and change. More details can be found on these pages:
Getting started with Second Life Has basic information on downloading, installing, and using the viewer software.
Viewer menu - Has information on the six standard drop-down menus that appear on the top left of the screen
Advanced Menu - Has information on the two optional drop-down menus that can be turned on: Advanced and Admin.
Context Menu - These appear when you right click in the 3D view area. Depending on what the mouse was pointing at, the menus will change.
Inventory Menu - The inventory floating window which lists the inventory of items you own has it's own set of drop-down and context menus.
Floating Windows - Many buttons and menu choices open a 'floating window' which appears on top of the the 3D view area. They appear to 'float' over the 3D view, and can be moved around to suit.
The Website
Some parts of the Second Life service are accessed via the website rather than the 3D viewer program. Both the website and viewer use the same account first and last name, and password to log in.
Some of the more important pages include:
- Second Life: Official Site - The main home page. The bottom of that page has links to many of the more important pages.
- Second Life: Join - New account registration page.
- Second Life: Your Account - Summary of your account, with links to other account functions
- Second Life Blogs - Official communications from Linden Staff
Community
- SL Forums - Discussion forums. Some Linden Staff post here.

Things to Do
Once you are all set up, there are many things you can do. Where you go and what you do are up to you, much as you can surf the web and use it for whatever you choose. There is not a goal, or way to "win" Second Life as there is in some online games, even though it uses similar graphics technology.
Some of the things you can do and hints about how to go about them are listed below.
Meet Other People from Around the World
Play Tourist
