A player with Black Brain Rook membership level can use up to 45 vacation days a year.
After some vacation days are used, it is possible (twice a year) to get some extra days (during the same year) if the player buys a year (or longer) membership (Brain Knight or Brain Rook) for another Brain King user - 10 after the first renewal and 5 after the second one. The purpose of this rule is that a Black Brain Rook member cannot purchase another year of a membership for himself because his membership never expires.
