Chris,
How about discussion groups with topics like, leaning, flight techniques, etc. the topics which usually generate the most chatter on the site. A chance for those in the know to spread the knowledge.
And not sure the gang would like something that involves the klux gang to give quick reviews of the baby beeches in attendance, for possible problem areas and or hit list of stuff they see that should be attended to. Might be better than an overall maintenance clinic, to receive some specific info about your bird, for those who can't or haven't made it to KLUX.
