Once a game starts, It does not always notify a person that the game has Started.
What if everybody press Start game button...then those who do not press (in the allotted time limit) the start button get kicked from the game.
Game would continue to wait for players.
@ the players who do not care if an opponent knows that the game has started. Maybe you should post a note on his wall. Who wants to score a win that way!
I for one wish to have the best game possible. I often tell my opponent what he might be doing wrong (while in game) in an attempt to have a great game.
