Josh, a very good point against quitters. But what about interrupted connectivity? What if someone's WGT client disconnects due to an error? Woudn't be very fair to give him any kind of penalty. Just my opinion....
Moreover, I would suggest a different feature. When the opponent disconnects, what about allowing the other one to continue playing in single-player mode? I'm really upset when I have a great round, the opponent disconnects and I'm forced to leave that round...
