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.
alanback: I believe you can put the person on your blocked users list, which will also block all in-game chat. They can still write to you, but you will never see it if I remember correctly.
You will not be able to get PM's from them either, but I'm guessing that will not be a problem.
