An Avatar is a specifically sized image that is either your photo, logo or a graphic that you want to represent you. There is a website that I highly recommend, which will facilitate your Avatar following your email address on anything you post information to, such as comments on blogs, including your own.
The site is http://Gravatar.com. 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!
