I've played Star Wars Galaxies and Star Wars the Old Republic, but I've never played Star Wars Combine, I'll have to try and check it out.
As for approving posts, I'm not exactly sure what to tell you. I'm fairly new here myself, but I don't remember having to wait for any posts to be approved. If you're still having problems, maybe contact an Admin. They're all very friendly, and helpful.
