Regarding social clubs

A social club is a place where people gather to fraternize and share common interests. The only way of becoming a member of a social club is to be invited by the club leader. All social clubs have a club house where the members meet.

VIPs can be a member of up to five social clubs at the same time, while non-VIPs can only be a member of one.
