Forum Chess takes the one-on-one mentality of chess and throws it out the window.
Forum Chess interfaces with a BBS and allows a team-based chess game. Up to four players can be involved with a team and can collaborate with eachother in order to win.
A web-based html chat system. Allows users to chat in multiple rooms, private chat, 2 player games (checkers, tictactoe, chess, etc..)
all without any client requirements other than html. Currently server requirements are PHP4 & apache & cron.
