Give Doc ban powers (If he hasn't already) And promote another member to a mod for this section, which will help with a quicker clean up.
Promote 3 users to a GFX team, give them smaller powers (Which i believe they don't have, i could be wrong) such as closing threads.
Better competitions, with better prizes and a better format. Such as use the same format as the world cup last 16, do knockout phases, as it gives the user a feeling of better competition, and i'd gladly buy and give the winner of that something like a starcraft 2 key.
GFX section should have a lot more flare in it. Right now it's the same, only a SOTW, nothing different. There should be new ideas happening a lot more, even if some fail, just to make the section more appealing.
