When you make a mission please remember to put the exact location of your mission in the mission description window and also on the first misison goal, otherwise many people will just ignore it. If its somewhere other than Vulcan or Bajor most people wont know where the systems are located.

So for example if you want your mission to start in the Seeda system of the Xarantine sector located in the Pi Canis sector block make sure you write that clearly in the misison description box, maybe even highlight it.

You can get away with your first goal (the stuff that appears in the mission tracker) as go to the Seeda system but just make sure that somewhere you tell them the sector block as well.
