I've had a few "run-ins" with the Irish music fascists at thesession.org, but there are some nice folks there as well.
A concept I'd not come across before on this site, is the session "leader". Any body that knows what sessions are all about knows that nobody can lead a session.
Another thing that they do if you piss 'em off is make up lies about you, masquerading as other people.
So if you visit make shore your on all fours, tugging your forelock and you'll be fine
