Do you miss something on BrainKing.com and would you like to see it here? Post your request into this board! If there is a more specific board for the request, (i.e. game rule changes etc) then it should be posted and discussed on that specific board.
coan.net: I'd be really disappointed if, in the case Brainking would get multiplayer games, the games were implemented as ponds currently: having to make a move once every 24 hours. Unless it would be games that are over in less than five moves, I'd never play such a game.
