I'm on a bunch of forums. Some allow embedding YouTube vids, most
allow embedding pictures. All seem to require considerable work to
maintain, and I don't get the impression that they are without cost.

The glider community could carve out a happy home on some existing web
forums that provide multi-media communication. A couple possibilities:

http://www.purpleboard.net/forums/index.php

http://www.pilotsofamerica.com/

Obviously AOPA and EAA have online forums, but they require membership in
those organizations.

One can also easily create forums on Yahoo Groups and Google Groups, though
I think Yahoo has some technical advantages over Google.

There are good options that don't require investing extra time and
continuing administration.
