I think having a team of moderators would be a good idea. The "first 3 posts being vetted" idea is also good.
I understand you guys would have a hard time allowing people who aren't in the "inner circle" of the six guys creating the game to have mod. privileges on your forum, but with a mod-log you could take a look yourselves at any changes/edits made, and take away that privilege if it was misused.
I think you underestimate how much aviation fans want this game to succeed, and hope you put a little trust in the "annoying nagging voices" you hear trying to give you constructive criticism. Anyone around here, besides the shoe ad. people really want this game to be as successful as possible.
Anyway, looking forward to Devblog #10: Jetbridges and Concourses ...
