I put up 6 invitations to play Backgammon, with the message "Please do not accept more than 2 games" (I like to play a variety of opponents, who might have different active time-of-day). One player then accepted all 6 games, despite my message. Is there some way to cancel some of these games? The player in question does not reply to any messages, not even to apologise for accepting all 6 games, even when I have translated the messages to his own language. (Needless to say he/she has now been added to my "blocked user" list, so it won't happen again, but I'd love to be able to just delete the unwanted games.)
