ughaibu: When a board is created as readable for public, its content must be acceptable [no rude words etc.] because this site is visited by children and I don't want to make people think that anybody can post anything to be readable by anyone.
On the other hand, when you create a really private board where only selected users can read/write, you can write anything you want. Until somebody makes a "leak" and reposts some of possible problematic content to any public board.
Please keep in mind that BrainKing is still mostly a site to play games. Discussion boards are only an addition and nobody will be allowed to ruin our good reputation misusing them.
