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.
Personnally I think there are too many single BKR`s. Perhaps would it makes sense to summarize BKR`s in groups for instance all Halma games,all Checkers,all Gammons ? In Chess I would like to see three groups: regular chess, chessvariations with regular board and set, and variants with bigger boards and additional pieces.
