Just because the command station is secret doesn't mean recruitment has to be. A group with the resources of the Taskforce could easily procure a ship with a high quality cloaking device to secretly bring newly recruited members to the station. Of course, this is probably just speculation. It probably is just recruiters seeking you out for as long as you fit the purposes of the Taskforce. Problem is, my character (if I even finish him) isn't likely to be very easy to find due to the fact that he is being pursued by a rather large variety of people, and because of the fact that he uses Force Stealth and Alter Image to help him avoid any of the force sensitives that are after him. Of course the Republic has far greater resources than either of these groups, whom of which I will keep ambiguous, but he would still be rather difficult to find. And even then, I don't know if the Republic would even want to recruit him, due to the fact that he has purposely obscured his past from the authorities and by the fact that he has gotten into a bit of trouble with the law.
