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 have requested this for over a year and have had the same complaints from other players and that is in checker games do not use chess markers I cannot see the reason or problem in this so if there is someone who can rectify this problem you will make a lot of players happier.
