Jeremy Linden has been working on the Second Life(TM) wiki, the Best Practices for building, mesh, animation, and more. Check out the main page: Good Building Practices.

Revised Wiki Page

This page covers all the aspects of building or making just about anything in Second Life. If you are building with mesh, check this out. It covers several aspects of reducing Land Impact costs.

I would say the place is being spruced up for the coming entry into Steam. Whatever, it is nice to the wiki updating.
