I've been trying to figure out how ConceptArt actually works. It seems like the Forums are seperate from the Profiles and Art Gallery, I find it quite hard to jump around stuff and view People's art. Example, I find this really nice picture posted on the forum, so I click on the user's profile to check other works, but his gallery is empty, the only reference is the sketchbook which is actually just a Forum post, and most don't even have one. I would pound on the admins to make the site more functional, it's all about user interface.
And also this place is way awesome, great stuff.
