How can I transition from a free books account to a paid books account?
I created a free books account (based on my existing itunes ID) to post 2 books just to test out the process. Now that I feel like I know what I'm doing, I'd like to update a paid book, but can't figure out how to go about doing it. I created a second Itunes ID to create a paid book account, but then the SSN I used for that account was the same (obviously) as the one I used for the free account and that's where I ran up against a wall. What to do now?
Thanks!
