The form change we announced a few weeks ago is now online on all gameworlds. If the form of your player is in the "red" area he will now receive less experience from his matches.
Make sure you pay attention to the form of your players. If it falls too low, play more tournaments, if it goes too high play more practise-tournaments.
The next changes will be in the graphical design of the site. We expect some updates in the next couple of days.
