Yes, I can add a script that will be automatically started once a day [like the expiration check script does] and will start all tournaments waiting for the next round. I will add it to my list.
About turning rooks to pawns, such player loses all rook advantages [directing a tournament, starting a fellowship, etc.] but he is not automatically kicked off his fellowships and tournaments. I would like to give people a chance to renew their membership, especially if they run a fellowship.
Since these situations [membership expiration] are still new and not much tested, I will improve them later :-)
