Could someone tell me in simple understandable step by step language how I could post a mission , load in the aircraft my friends want to fly and post it so as we can play online. Thanks guys

You don't have to post it anywhere.

They'll download it from your server automaticaly when they connect.

Every answer is a question. ??? How will my server have that info?

Ok lets see if I can make this easier....I have downloaded hyperlobby and have a mission ready....what next???
