Stiletto Girl gave me ten credits for my birthday so I could buy the CSS upgrade. I am an over-researcher and want to learn a lot more about CSS before signing up for the upgrade and beginning to mess up my blog as I am sure I will do. But do the credits expire in a year from purchase, or does the upgrade expire a year after I click to get the upgrade? Right now the credits are just floating around in Matt's bank account, not associated with the upgrade yet.
Is the expiry date a year from credit purchase, or a year from upgrade-getting?
