It's not about the numbers here. It's about the decrease in activity. Remember the "GFX Battle: Freestyle"? Only I posted my entry out of 5 or 6 people entered.
Yeah, sorry 'bout that. It's that the activity in the boards is decreasing. Unless there is a prize involved, I doubt there'l be enough people/quality for an art contest.
Hmm ... how about 10 bucks for the winner? Just like the AO Rank Image contest.
