I for myself think that the turn limit with 5-7 days for a move is much to long and I don`t play such tournements.Games with long turn limits will take an endless time until they are ready.
Why don`t you play a little bit fewer games, then you can play games with a shorter timelimit and it would be also good for the capicity problems of the server.
Btw I think as a rook you can define your own tournement.
