I see that any commander can be ATC on the Training Server. But a big question I have is that if I can be ATC on the Expert Server, without being from IFATC?
You have to be a member of IFATC to control on the expert server.

You must be an IFATC member to control on the Expert server. We are put through some rigorous training to make sure that us, as controllers, are prepared for anything that may arise. See above post if you’d like to become a controller as well; We’re always happy to expand our team!
