For posting: - invitations to games (you can also use the New Game menu or go straight to the Chess Invitation) - information about upcoming tournaments - discussion of games (please limit this to completed games or discussion on how a game has arrived at a certain position ... speculation on who has an advantage or the benefits of potential moves is not permitted) - links to interesting related sites (non-promotional)
as for me, I'm still active in the IECC, which is an email chess organisation, but have slipped to only 1-2 games since IYT, and then GT and BK became active. it's simply too comfortable to play on a server.
