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.
The button makes lots of sense, but think about this (devil's advocate) point, If someone sets up a tourney with ALL games listed, would you sign up for everything????
