I've been curious about the fact that there are different moderation styles in the two forums, pre-merger.
For example, it seems to me that the AA forum tends to have more threads merged ("mega-threads") while US lets new threads remain standalone. Also, the US forum maintains threads for their hub airports "A US Guide to CLT", while the AA forum usually moves airport threads to the destination forums.
Have the moderators decided yet how you will handle differences like these once there's a single forum?
