In the "What feature would you most like to see on BrainKing?" poll, I'd have liked to be able to choose this:

Enable some means for either Brainking or a tournament creator to enforce the ratings range that is specified when one creates a tournament.

I've seen tournament entrants that did not meet the minimum.  If that's allowed, let's not bother specifying a range or else make it clear that ranges are merely suggestions or requests to tournament entrants...which might not be honored or noticed by those signing up.
