I started up a Game Jam. http://www.newgrounds.com/bbs/topic/1350730 Thanks to TomFulp for putting up prize money and for saying he would judge. Thanks to Luis for saying he would judge as well.
EDIT: New thread in the Art forum to attract some artists to join. http://www.newgrounds.com/bbs/topic/1350852 Both are open and fine to use. Just pick one and sign up.
EDIT: Since I've recently been banned (I know so sad) I will ask a mod to lock the thread when sign ups for the Jam close. So if you go to sign up and the thread is locked that means sign ups are over and you unfortunately missed your chance to join the Jam.
