Problem with Gravatar? Not Receiving the Confirmation Email.
I came across with this problem while registering the Gravatar, and finally found a way out by myself. So, I'm posting this blog hoping that I could help you to solve your problem registering with Gravatar which might be the same issue that I'm facing.
After register with Gravatar, did you face the issue of not receiving the confirmation email(to a forward email) even though the system said confirmation email sent?
It's hard to get direct support from WordPress if to compare here in WA. I searched the 'Q&A', 'contact us', & 'forum' but none of those helped me out. So I figured out a trick by myself as I really wanted to use back my firstname.lastname@example.org email for the Gravatar image which didn't received the confirmation email. At first I thought that it might due to the forward email issue, but I tested out my forward email with sending and receiving a test email, they worked out just fine.
You'll need to login using WordPress Account at the top of the website.
Once you're in your account, under the 'Account Settings' section, change your email address to a dummy email(not a forward email). After you have changed, you'll either be able to receive a confirmation email from WordPress, or you'll need to re-login again to resend the confirmation email. Now you have an email confirmed account to login Gravatar.
Once you're in Gravatar, you can add the email you like, set it as the primary email, and delete the dummy email if you like.
I hope that my post will help you out if you got stucked with the same issue that I faced, it took me 2 days to figure this out(frustrated the whole time in these 2 days!). And as usual, please leave your comment at the below if you have any question, and I'll be more than happy to help you out(Kyle's influence).
Updates 2016.01.30 - One of our friends, Kristena Calhoun found out a solution for a funny issue she faced which the website kept taking her to the confirmation email sent landing page when she clicked on login at the top. Thus, she couldn't proceed with the trick that I provided above.
What she did, she cleared out her browsing history and went back to the login page. She logged in and went back to the confirmation email sent landing page, clicking the contact us at the bottom brought her to another page which it tells you to go to the community forum. By clicking on it automatically had her logged in, then she followed the trick which I provided above.
Hope this information will provide a solution to those whom fail to login and being lead to the confirmation email sent landing page every time.
