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.
I just looked, but if the 20 game limit is the reason then Pawns can't anyway. Also being Pawns we have to wait for the first BK tournament to finish, as we can't enter more than one :(
