If you are looking to join a club, then you should perhaps look at the Club List thread.
It contains a large list of many clubs recruiting users, along with what types they are and activities you can participate in.
Other things you might want to consider (in additionto the list):
Post your interests.
What would you like from the club?
Are you interested in a club that becomes involved with public/private events?
What about meetings?
What are the club requirements, if any?
Answering these questions might result in an invitation for membership.
