How about sending an email when the opponent resigns (or when a draw is accepted--haven't had this happen yet, but I assume you don't get one then either). I'd like to be notified when a game ends; sometimes it can be easy to miss (especially if you usually filter by 'My Move', etc.)
Yeah good idea;
and I would like some way to know if you had offered a draw in a game already. Sometimes it can be hard to be sure which game it was offered in,or even if you had offered it at all.
I can imagine it would be virtually impossible for subscribers with hundreds of games in progress.
