Skyline Soaring CLub in Virginia www.skylinesoaring.org is right up
there, and while it's attractive to newbies, it's primary focus is
meeting members' interests and needs. It's actually more than a club
website, since the Club owns/manages the server which, in turn hosts a
whole bunch of Club goodies, e.g.:

1. The website itself, with several layers of highly secure limited
access section (e.g., for instructors, members, Directors, etc.)
2. Automatically records all the Club's operational and financial
records, updats them electronically from a laptop at the field after
each operating day. Then provides huge database for mining for
management information.
3. Houses a sophisticated instructional progress tracking system
(available through the secured "Instructors" section of the "Members
Only" website.
4. Repository for Club documents
5. Distribution system for the newsletter "Skylines".
