Calm down guys.
lord voldemort, you really can't lay claim to tournament ideas in advance. If you want to do that you need to announce the tournament with the stipulation that it will not be starting until a certain date. Besides, there are already multiple Age of Realms tournaments in motion already.
As for updating tournaments, you should not expect your players to wait weeks on end due to one player taking time off for personal reasons. I know it sounds harsh, but if they are going to take time off from the site, they are also forfeiting whatever standing they had in tournaments as well. It isn't fair for all of your other players to have to sit around and wait for one person. It would be different if the game was still active, but once it finished they new ones should have been made.
If your exams are taking up too much of your time perhaps you should think about notifiying all of your players that you will be taking a short vacation and then be back. That usually helps in player retention, but just not showing up does not.
If you have any further questions, feel free to send me a PM.
