accept to start a game
This post is related to the iphone app.
I would be better to accept the start of a game in the menu. Every time I want to have a look trough the menu (e.g. "Free-Match") a game is imidiatly started. Specialy in the beginning when you dont know the game structure you'll lose many points and frustrate other people after leaving the unwanted game.
I have a bad karma level now because I wanted to check out the game without playing (as a game takes a while to finish, nothing for your 5-minute-break at work )
You could place a message like "are you sure to start a new game?" or ask all players to start a new game, or ...
That would be sweet.
