Great game

[Christocipher]

Hello what a great game😀 The detail is amazing and I am really enjoying playing but still getting used to some stuff. So I put a whole lot of questions in here. So how long is a turn, When I play a Scenario as PBEM can I check the other players preferences, When I select between different planes the different exit and entry points dont update, sometimes I get a rough terrain warning sometimes I dont is that meant to be

Can I anyway limit how many of some things there are maybe like some german things that they only had 1 or 2 off. In a game can I put down some sort of marker like a waypoint to remember a place.
