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.
tonyh: I know it's not the answer you are looking for, but what I would do is get some blank overhead projection sheets (Clear plastic paper), put them in a small binder. Get some dry erase markers and just draw your boards out. Very easy erase/write - you can make your board "big" and put a list of 3-5 pieces you might think is in a certain spot, etc... a lot more then what you could probable do with an on-line note board. (plus easier then to have Fencer program it also!)
