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.
Fencer, I too am curious why you don't like it. But the question I have is...Is Brainking purely for your own enjoyment or is it a business venture? In business ventures, typically the developer's likes/dislikes takes a back seat to what the customers want. The more customers, the more money. I suppose it could be a performance issue.
The more I think about it, the more I like an auto-pass feature that is enabled/disabled when the game invitation is created. It would be nice for me not to have to wait for my opponent when their only move is to acknowledge a pass.
