The International Email Chess Group has an FTP site too. Here are some good places to talk about computer chess and other matters discussed on this page. Please don't mail me questions about these lists. The Computer Chess Club is a Web message board for discussion of computer chess. It's moderated in an attempt to prevent flame wars.
Membership is free.
Volker Pittlik runs a Web message board called the WinBoard Forum . Some posts are in German, some in English. There is a Crafty mailing list. The list is moderated to filter out spam and flames. Others can join, but you probably won't find the list interesting unless you write software that speaks the chess engine communication protocol used by XBoard and WinBoard.
