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.
Yes it does. I believe you need to have at least 5 open game slots in order to play in a tourney if you have a limited account. Perhaps Fencer could confirm this for us.
I will be holding many more tournaments MadMonkey, so you'll get your chance. There are other tournaments open for signup at this very moment that other people are holding too.
