Hi,
In supcom we have this problem a lot... you have to wait some time until the game is full and when its full some people are browsing the web etc.. and you cant tell them the game is ready to start.
So what I suggest for Demigod is implementing a ring button for the host, so he can tell/notice people that the game is ready to start and they have to ready up.
Because in a big game you have to wait until you get 10 players in the lobby and people will tab out and do something else while waiting, so it would be very nice If the host could ring them and people get the notification so they can ready up and you dont have to kick them.
