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.
AbigailII: Sorry to get off topic a little, but for what it's worth, there are games on this site where you have to remember the previous board position to play well. (For example dark chess, espionage).
