Just wondering isn't there a way to disable the redX button on peoples browsers so the only way a player can leave is to press the forfeit button. It would take away all the complaints of people just quitting in fit of rage when they play a bad shot,
You could put a mouse-over message on the redx that tells then its been disabled and to use the forfeit button
or make the forfeit button more visible, i swear some people don't even know it exists.
