Once started, players are responsible for arranging the match play with their opponent via Eliters Messenger (EM). Opponent Email will be available by clicking on opponent’s ID, to assist in arranging the match. Players may also utilize IM, however, these will not be taken as valid attempts for Win Claims purposes; valid attempts made using EM will always count more in any decision the TD may make in advancing players should the match not be played.
Valid attempts consist of offering at least a full 2 hour period of availability to your opponent, with enough advance notice before the suggested time periods; avoid setting up an exact time just 1 or 2 hours ahead and expect your opponent to be there!
I know a lot of folks are hanging out in the lobby hoping their opponents show up, it wont happen. Don't get frustrated and waste a lot of time when you could be playing and having fun
