new live chess

The biggest improvements are 1.) A LOT fewer disconnects and 2.) The ability to re-connect when you are dropped.
Yes, some features were actually taken out, but those will be added back in for the next version of Live Chess.
What are you talking about there are and will be many improvements. Just go to this link and check it out.
