So here is an article about how to sign up to get your own gravatar. But before we dig in on the details, let me explain to you first what a gravatar is. Your Gravatar is an image that follows you from site to site appearing beside your name when you do things like comment or post on a blog. Avatars help identify your posts on blogs and web forums.
So here is how to do it:
1. Go to the Gravatar home page.
2. Click on Sign up.
3. Then enter your email address and click sign up.
4. Gravatar will send you an email for you to confirm. Simply click on the link that Gravatar sent you or paste that link into the url field on your favorite browser.
5. Fill up the username and password.
6. Once you have entered your username and password, you can now choose an image to use for that address.
7. Once you uploaded your picture, you now have your gravatar and everytime you post comments on blogs or anywhere, your picture will now appear beside your name. You can modify and add email accounts also in your Gravatar account.
Hope this tutorial has helped you in some way or another. Thank you.
