How about a feature to end a tourney once it is already decided who will win? For example, I have won all the games in a running tourney that may not finish for another year or 2 because a certain pawn who has more than 2200 running games is involved. My last move was October 5, 2011, and one of the games (11 pt match) is still at a score of 3-0. Until that game ends, as a pawn I cannot join any more tourneys.
