I would like to suggest that elimination tournaments are not going to be deleted if the destined number of players were not reached. Currently you can't set a minimum number when you set up an elimination tournament, so if you set it up with 16 players, it will be deleted if only 15 have joined. Why not give one player a bye in the first round and let the others play? It's an elimination anyway, so from round two on it will be no difference any more. One could set 4 players as a system default minimum number, and every tournament with more entries will start as usual.
