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)
If you click the settings link on the left column, and scroll to the bottom, there is a checkbox there called "Notify by e-mail if the opponent makes a move and I am not on-line". If you make sure this in unchecked, it should solve your problem :-)
(hide) If you are waiting for your turn, click on "change" next to the "refresh" on the main page, then set refresh the page to 30 seconds to get your turn to move displayed faster. (Servant) (show all tips)
