I'm pretty sure that either side is open, but on that not you would need to confer with an actual GM, but as far as character creation goes, I can give you a hand, PM me with what you have, plus any questions.
As far as posting on Korriban goes, and you should prolly double check with theUnkowable on this, but my understanding is that we have fast forwarded it a bit on that planet, so I've been established as a security chief for a couple days now.
