I had a couple of thoughts, and before you say “No! No more sections”, please think about it.
Why not make the “WIP” section 3D only (as it almost is anyway). And why not make 2D artwork a 2D WIP/Finished combination (as it almost is anyway as well). It alway looks a little lost when I see 2D stuff in the “WIP”. This would be a minor change anyway. (People are also posting modeling work in “2D artwork” lately, btw… )
An idea for a new section: “Joined forces on cgtalk.com” where a 2D concept artist and a 3D modeller can meet and work on something together. Like Need a 2D brainiac in 2D artwork: http://www.cgtalk.com/showthread.php?s=&threadid=12251
Those threads are very exciting. It could also be a very good experience for semi-pro’s or people just starting, to learn how to work in sort of a team, instead of running around in the little circle called “their own mind” 
Anyway, see for yourself what you do with my little ideas.

(btw, about that adult-stuff thing. I hope it wasn’t me. I did post some Photoshop-paintings of naked girls, but ehm… I also did ask how far I could go… and one of the moderators told me something like: “As long as you don’t show sexual activity, it is called art and you can post it…” )
edit - I am referring in this “btw” to the thing Leonard said in one of his first post in this thread about some magazine saying cgtalk did host adult stuff. Not to the later discussion about some ***holes posting pornpics
)

I’ll be quiet now.
