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)
Tuesday: That's as good a method as any, but watch it! You might find that you like the game, and then you're hooked for life. No patch or chessoholics anonymous will save you. Be warned!
