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.
SunFire: I think you can do that by going into Settings and then, on "Sort next game by" choose "time of last move" ascending.
Haven't tested it though because I don't have any waiting games right now
