Nagana & Bora-Kai in my campaign

I have been a big fan of this site for years, and have been using ideas from the Star Frontiersman in my own campaign.  (thank you guys!)<br /><br />I was just wondering about the Nagana and Bora-Kai.  What have other people done with them?  <br /><br />They have been a part of my campaign for a while now, and sometimes I forget that they are fan-created aliens.  I have yet to have any of the players use them as PCs, but then I've never had anyone play an Osakar or Ifshnit either.  Anyway, my players are just about to visit the area where the Nagana live, and I thought I'd see if anyone else uses them.<br />
