So I had my wife create a new account and make it premium over a month ago. She sheepishly admited to me yesterday that not only does she not remember the spelling she used for her name, it turns out the email address that was used to create it was already attached to a seperate SL character. So, what I have is the email she used (or re-used as she only has the one), and a Credit Card number. Will that be enough to retrieve the rest of the account information? Thanks, Antaeus
