You don't need Station Access. Get a paperdoll image while in game. Then sign in to EQ2Players and view your character. Scroll down and you should see a "Forum Signature" box with links to the sig as well as a link to add your paperdoll.
A quick search on the EQ2Players.com forum for "signature" turns up lots of useful stuff, like this post I made eons ago: http://forums.station.sony.com/eq2/...=351398#3982470 If you also want to upload a paperdoll, there are instructions at the bottom of the first post in the stickied "How to Use Your Sig Graphic" & Sig FAQ thread.
