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.
Not sure if there is a practical way to do this. Maybe some feedback...
Since in many games white has a big advantage, is there a way to make seperate ratings for games played as black and as white? I havent looked, but would bet that some people use playing white against unknowing opponents as a way to boost their ratings.
