Also: download a well designed mission (if you look on sites like mission4today you will see familiar names of people who have posted a lot of missions).

Then, look at the mission in the FMB and tinker with it---see how someone who is experienced has designed a mission.

So, you can start out by changing or altering already built missions to your taste--before you start on your own.

Just a thought.
