I have been stuck! For several days I have tried numerous things to get a confirmation from Gravatar for the email associated with my website. It has been sooo frustrating! Today I finally found the right training here on WA. It actually wasn't the training but a comment from someone that cleared up the problem.

To finally have my new email address associated with my Gravatar, I went to an old Gravatar I had that was not linked with WA. I logged in, added my new email, got a confirmation, then I changed that email to the Primary email for that Gravatar. Whew! I'm glad I stuck with it and didn't give up.
