Is there an appropriate place to suggest new Stack Exchange based sites, perhaps a place for them to be voted upon?
I wish there was a Stack Exchange site for Aviation (both real-life and simulated).
Meta Stack Exchange is a question and answer site for meta-discussion of the Stack Exchange family of Q&A websites. It only takes a minute to sign up.

There currently is a proposal up for General Aviation. You can follow it and participate in the beta, if/when it gets enough traction.
