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.
Actually that option is still there - Fencer just "hid" the buttons! So if you know how the site works, you can still ban and hide a user. (until Fencer reads this and then he actually turns off the option) :-)
