Does it matter if you change your gravatar email address?
I want to change my gravatar email address as it refers to my old site and I have a new one I am concentrating on now. I suppose I have two questions really - does it matter which email address is attached (i.e. does it matter its an old one I don't really use) and if I change it will it affect my google rankings at all or is that irrelevant?
Also, if I do decide I need to change it, how do I do this?
