People form a group, one of them goes to the station and takes the mission, a certain amount of stuff has to be delivered somewhere, anyone in the group can deliver a part or all of it.

Purpose is to encourage group activities.

Missions should range in size from a few hundred cu for newer players to a few thousand for higher level.

Each member needs to deliver at least one cu to get credit.

The advanced missions should pass between nations or to/from grey

This would be fun! Escorts but with players. Honestly I'm disappointed I didn't think of this!
+1

I’m just starting to think about trade again now that I’m running out of credits.

+10 for me
This sounds very good and would bring traders together.

+ 1
more trade content and missions

Convoy!

Oops is this something I could have done in the PCC editor……

YES. A large group of targets makes it more likely that I'll be able to splash at least one of them.

+1 to basically anything that encourages group play, and this one could be particularly neat.

+1 for more group missions
