I have a question. When I pay for a dropbox account, if I need to check my billing, would I be able to tell what e-mail dropbox is under when looking at my bill monthly? Is there a way to ever find this out if I needed to? I am trying to pay for my dropbox account with a credit card but I do not want the owner of the credit card to know my e-mail address that is used with this dropbox account. Just checking if there is a way to trace back to the e-mail based on billing and credit card info only?
