I personally dislike the people that don't resign! Yes, I know it's perfectly within your rights to stall 'till the last hour and play all the way to mate but at a certain level in CC play no one is going to blow a 9 pawn advantage!
It would be nice to have a way of avoiding rematches against people whom you've had these experiences with.
Having some sort of ignore list that allows me to filter the people that can accept my open challenges... so far I've played against 2 (of 100 or so, so I'm rather happy) people who have been extremely ignorant..
Figured it would be a good upgrade to a simple chat ignore list..
Hopefully someone is with me :)
