Being able to schedule matches is great, but there should probably be something in there to keep people from entering extreme challenge dates. I just got a challenge for Dec. 31st.
Also, out of curiosity, if I were to accept it, and both of us forgot about it -- what would happen? And what happens if somebody schedules a date then goes into hibernation before the date of the match? Is there a way to mutually cancel a match if it's been accepted?
Sorry, I've been gone this weekend and haven't had a chance to actually compete yet, so most of these questions probably have obvious answers once you've actually played.
