It's a forum for general graphics design stuff, but it also has a section for 3d Design (or 'Renders' as it is there ). I don't own it, but I am a Moderator there, and head of the Renderers section. (which, as of now, consists of me)

We're a little short on members (around 15-16, half of which post)

And I'm also known as Andon there.

EDIT: *hits head against wall*
