Czuch: I've noticed at least a player (that has two games of a team tournament against me), that has about 15 vacation days set up, and everyday he removes the nearest one, and adds another about three weeks ahead. This way, when he moves, instead of having 5 days per move, he has 25 days per move (and he has less than 50 games...).
I already sent Fencer a message telling him who the player is, but since there has been some problems with naming,players, here in the forum, I won't do it.
That message was sent yesterday when he had the days between 13th july and 31st july has vacation (and 17 vacation days left). He now has the days between 17th july and 4th august (and the same 17 vacation days left)

Unfortunately it is still possible to take advantage of the vacation system...
