Here is my referral code for 
Loki Cash. 
Loki is a GREAT guy.  I spent an hour  with him touring his parts of the virtual world he has built, and I'm in the process of creating my own store at UV. 2 million members who like virtual "porn" = great target audience for my 3D sites. 
After a lot of thought, we went with an avatar called 3DFiends and upgraded her to premium.  With that name, either Jim (who goes more often as Renderfiend now) or I can use it, and we got the domain 
3DFiends as our hub for our 3D sites, which I built yesterday.  I plan on having a webmaster section too with links to my toon sites other webmasters can promote also, and we are considering putting up some of our older toon content for sale as a package for anyone who wants it for pay sites, or AVS sites, with limited number of sales.
I really enjoyed the talks both Friday (I sat in on all of them) and Saturday.   I met a woman who designs clothes for avatars in there, who has a virtual store that would be the size of a 3 story big box store, it is amazing what people have done in there.
