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)
When a draw offer is sent, a private message is also sent to his/her mailbox. If your opponent moves then the draw will not be accepted, if your opponent doesn't move, but doesn't respond then you better move or your game will time out.
