Once I figured out the basics of avatar fashion in Second Life, I wasn't sure what to do next. I thought maybe a little building, maybe a little scripting .. but more so I could have a good time, not to become a hard core builder or anything.
This great newbie Second Life guide from Ariane Brodie gives examples and links of what to do after you figure out good skin, hair and clothes, including teleport scripts, camera controls, jewelry creation and attachment scripts.
You can certainly enjoy Second Life without going into this next level of basic scripting and creation, but it's really helpful to have links to these basic scripts and how to implement them into simple prims.
Ariane also writes the Life in the Metaverse blog; recently there has been an interesting series of real-life builds in SL. Some great places to check out!
Thanks to Gwyneth Lillwelyn for the pointer!
