"Come on, roll a healing Jedi, we need a 5th man."

If you have a friend into TOR and you wanted to give it a shot, it looks like you got your chance - instead of waiting for a free weekend, get him to invite you, as he now has quite a few spares. The original number of free invites allowed were three, and instead that number has been increased to twenty five. So, yeah, you can definitely get a few friends to play.
