Web-based software to maintain a database of past and present members in a club, including membership status, mailing list membership etc.. There is both a limited view open to the public (or members) and a full view and editing interface available to administrators. There is also a form for people to join the club and be marked as provisional members until an administrator confirms their membership (perhaps after they pay a membership fee).
Written in PHP, using PostgreSQL as the database backend.
