Officially I'm not a member of LSF anymore, because I don't have the time to come to meetings etc. But I'll probably try to make some time when JK2 is out.
LSF is one of the biggest and oldest Star Wars league. You can play most SW games there (JK, XvT, XWA, SWG, etc). You don't have to be an elite player to join, so newbies are also welcome.
For more information, look on <a href="http://www.starfighters.com/lsf") target="_blank">the LSF website</a>.

(I just wanted to have the first REAL clan recruitment message here :D )
