An Avatar is a specifically sized image that is either your photo, logo or a graphic that you want to represent you.
Make it easy and register with Gravatar.com so that your avatar will follow your email on posts and comments.
I highly recommend that you do this in order to make your “mark” in the world. Gravatar’s service will facilitate your Avatar following your email address on anything you post information to, such as comments on blogs, including your own.
Create an account, include your desired Avatar, profile pic, biographical or company information and the email address you use to make posts. Now, whenever you make a post, your Avatar will automatically follow your email address, where ever you post – and readers can click on your Avatar to get more information about you and learn where they can find you online. This is a must for driving traffic to your website as you work towards building relationships with other bloggers!
