In my research about certain Mid-East airlines during the time that a forum was advocated forr QR, it appeared that tthe numbers for ssupport and traffic / questions in the forum were an effect of membership of an alliance (or in QRs case, being able to credit QR miles to *A carriers).
On this logic, I can see a lot of people who supported QR'ss secession to its own forum, appeal for OZ to keep its own-forum status, because it's a piece of the *A redemption puzzle. FTers come and stay here for status, miles and points and that's the crux of the forum organisation, IME.
As another *A person, still with miles to burn, I'd urge you to consider forums along alliance lines.
If an individual airline is not dealing with the alliance, then off with the gloves.
If it's dealing with the three alliances in terms of useful benefits for FTers, hands off!
(Otherwise, BA/BD would need to be merged into a LHR-based airlines forum. Just kidding.)
