TigerTom's Chat Room Software (TTChat) is a simple chat room with some surprising features. It's an easy set up. MySQL is not needed; it uses flat files. The membership database rotates; old users are dropped, so it's low maintenance. Designed for low server resource usage, while being easy to maintain. Has a bad word filter. Has a 'reserved names' option, so names like 'admin' or 'moderator' can't be used.
