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.
grenv: Might I humbly suggest that a decent autopass system in Backgammon, and a proper grading system would be much better candidates for discussion under feature requests than adding a few more (pretty useless) smileys.
