I was surfing the net and came upon an art community site called www.eatpoo.com, their forum is very active, like pixelopolis, they have finished works, general discussion, and activities. But they have something that this forum doesn't, weekly activities. It is in which an  assigned admin (or someone else, not really sure) creates a topic for an activity every week (For example, zombies, Draw my character, etc.) And I've noticed that their forum is much more active than this one and more advanced in means of art. Maybe if we create the "Weekly Activities", we will certainly improve ourselves and looking for something to draw or to "pixelate" will be much easier. At least the inactive pixelers will have something to look forward to, and something to participate in to. Ok, that's just my suggestion. (P.S. here's the link to the "eatpoo art community's weekly activities" :  http://www.eatpoo.com/phpBB2/viewforum.php?f=19
