I think most of the EAA clubs have some sort of email list or discussion forum for their chapter, possibly via old Yahoo!Group, .io group, or Google Group. Would the EAA forum software be able to handle a private thread for a specific EAA chapter? It could be linked to the member list, and so active members of the chapter could view that thread along side the other EAA forum posts, but it wouldn't be open to the everyone. That makes it easy to come to one spot to view both EAA discussions as well as get info on our Chapter's fly-outs and things.
