Yes please, remember that it's only one screenshot per player. It will help avoid a slow down of the forum, and it will be easier for us to admin the contest ^^.
By the way, let's say you'll be able to change your screen until the very last minute, as long as you just propose one screenshot.
Some players asked us if mods were allowed. Absolutely you can use whichever you want, we just ask you to not use any photoshop or gimp software.
Good luck to everybody!
