i think it would help games to have the server time displayed somewhere, so you can plan when to attack. Nothing is worse than just starting your go, just as the last dude in the previous round finsihed his go, and then halfway through your go he attacks your newly claimed land.
With the server time displayed, you will be able to better plan when to take your go, and try and make sure that the previous persons who went last in the last round, will not get a quick succession of goes...
my 2 cents...
