Last time mention was made of a "members council" to look after the checks and balances, a certain Australian forum was threatened with legal action for using the word AOPA.
Such a members council could look after appointments from a list of available. I doubt however you can elect someone without them taking on the responsibilities of a Director, so a four person elected team in reserve would not seem to be possible.
Re the constitution, I would strongly support going back to before the Smith Munroe Hamilton days and removing all convenient amendments thereafter.
A strong representative body is definently needed and AOPA should shoulder that responsibility. It's not the organisation that is broken but the succession of people running it.
Fix that problem and I may rejoin as a member, (although it seems moves are afoot to prevent me from rejoining because I didn't say nice things about them).
