Interested in learning how to "do" things in Second Life like building things, scripting, making clothes, etc.?  This is the spot to add those links.

College of Scripting, Music, and Science (Mature--though seems PG)

When you see some thing doing "something" in Second Life, a script is likely involved.  This would range from a door opening when you click it, to teleporters, to HUDs, etc.  If you want to learn how to make or modify scripts, this is the place for you.  There are 8 levels/floors of tutorials, ranging from "beginner scripting" up to "Rotations & Pi Math."
