I have noticed some threads about building missions for flying on-line. Is there a certain tool that needs to be used? I saw the limitation for flying online with the campaign and we would like to get a few more people into the air. Any help would be appreciated for building or generating missions. Thanks.

The program Missioneer+ will allow you to extract the last instant action, last quick mission and last campaign mission and then let you edit it to your hearts desire. It's still available on the internet and not too hard to find, but you would have the best luck if you google for it.

I believe PosGs site had it at one time, maybe still there.
