You haven't seen the [url=https://docs.google.com/spreadsheet/ccc?key=0AkqYweu36eUHdHVNbkNBVGZhSjFaVW5CYkpuMHRMbGc#gid=8]'levelup rules'[/url] have you?
Oversight on Kads part in setting up the first post I suppose, outlines the difference between darths/knights/colonels and apprentices/padawans/lieutenants, also provides details on what we mean by max rank, its kinda important as you need your starting funds to 'set them up' as it were.

That document also details the process of leveling up during play, your characters aren't all static after all. And if you poke around the rest of the document you'll see other mechanics, mostly the financial ones that we keep track of.
