There's a new membership-based discussion forum


I don't understand the advantage of such a forum over Usenet (except
maybe OT postings, which I can skip).

Then you're the only one. The Cessna Pilots Assoc maintains a web board
that easily gets 10 times the posts that this group gets. If there's
something you want to know about your Cessna that's the place to go.
