A Gravatar (Globally Recognized Avatar) is the little picture that shows up next to your comments. They're cool because they work across many different sites that use them. Here's how to get your own:

1. Sign up with Gravatar.com

2. Your avatar will be rated and then accepted.

3. Make sure you post your comment on this site using the same e-mail address that you signed up with.

4. Your chosen gravatar will appear beside your comments as a 64*64 image, providing it has been rated PG or below.
