I due have a suggestion. I think the "Flight School" board would be better off under the Sim boards. Because a lot of people post topics [in the Sim boards] that really should go under the "Flight School" board, but new members just don't see it, or know it exists. And for new members with questions about "how to fly", the right board would be at the top and it would be easy to see and access the information quickly. There could also be a FAQ sticky at the top to help newer flight simmers, and stop the same questions being asked over and over again.
I would also move the "Adding AI traffic and gates" board to the design area.
Just a thought...
