HI there, I haven't bought any credits for some time and have recently changed my email address-it was yesterday in fact. Could there be a problem in purchasing credits with the new one?

I don't think there will a problem buying credits for your account with a new e-mail address. You are in your iStipper account when you are using the buy page, and credits go to your account, not your e-mail address.

Most of the users here are smarter than I am though and will probably disagree with me.

@Chicsans, okay, thanks. I'll see how it goes within the next hour (after the caffeine has had a chance to kick in).
