On the Compello map, if you fly south or north off of the map, you will not leave a dar signature where you are located. Your dar signature or arrow will show on the corresponding grid square on the other side of the map. For example, if you are flying two sectors south on the map, your dar bar will show up two sectors down from the north side of the map. I have screen shots to further explain but do not handle computers enough to figure out how to post them. I will be emailing them to a squaddie so that he can do it.
