Q. What is a gravitar?
A. A gravatar, or globally recognized avatar, is quite simply an image that follows you from site to site appearing beside your name when you do things. Avatars help identify your posts on blogs and web forums, so why not on any site?
Q. Thats cool how do I get one?
A. Signing up for a gravatar.com account is FREE, and all that’s required is your email address. Once you’ve signed up you can upload your avatar image and soon after you’ll start seeing it on gravatar enabled sites!
