I tend to play a lot of web games, so I like to have a notifier of some sort to control if I'm about to forfeit a round or game or whatever.
Anyway, for this I think the email system works well, except it's too late. Every time I receive a "5 hour warning" it's in the middle of the night or something, and by the time I wake up and get to a computer it's already over. Add to that working full time, and I can't really my computer that quickly all the time.
I just propose you either have a setting for how long you give notice for, or that it be changed to something more reasonable like 12 hours or even a day since right now my turns last at least 5.
Thanks
