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 two feature requests about checkers: 1) post the rules... preferably with a short description of the main features in each one and not based solely on references like "same rules as Internacional checkers but with a larger board". With so many similar variants being able to find the basics of the rules on a first click is a must
2) make a different border color for Czech Checkers and Corner Checkers (and possibly others). I just found myself playing CornerCheckers thinking I was playing Czech Checkers...fortunately by the time I noticed it I was winning already
Marfitalu: how about fencer make some kind of encoding system like [add checker rules here] so instead of seeing like checkers but ... you see all the checker rules in a little box labeled checker rules.
This way all 22 languages or so can very easily refrence other game rules.
