On my last event at MDW there was some confusion on which server to put it on. I eventually just put it on training server so there would be no problems. But is there a requirement for making events on the expert server?
Make sure that all your attendees must be Grade 3 or higher, as the minimum required grade to fly on ES is G3.
Apart from that, you’re good to go!
There is no required server, though. You can host your event on any server.
Alright if someone can please close this now.
