Ok, let me try and reply to all of your points. First, I've downloaded missions from the tute section in the editor, and if I remember correctly, (and it's been a year or two since I downloaded these) there wasn't that much in the missions.
Second, macguba shot my idea down in a ball of flames.
I can learn a lot from BIS' missions (thx macguba!) and I have no logical answer to your last questions.
Third, whenever I try and DePBO
MOST missions it turns out the description and mission files and that stuff are in either (and I am not making this up) Czech or that funny computer language , I'm not sure which. So then they won't work in the editor. Thanks for all your help guys!
