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.
wetware: If there's a blot then presumably you could come off and therefore the option to double could become available again. This need only be for when there is no chance of coming off and rolling is not necessary...
