Nail is right, we really need the power to add, remove and replace players.
Another problem is the Tournament Tree, sometimes when there are 8-16 players, it fills out the wrong parts of the Tree, so the winners make it to the Final, but you can't actually advance the players who got Bronze, instead of having some at the very top, some at the very bottom, it fills out the very top and the bottom 20 or something lie empty, and the advancing is all wrong...
