WordPress 2.5 brings a lot of new features to the table and one of the interesting things is avatar icon for the comments that you made. Originally I thought I could create a small database of avatar icons for readers to pick, but smarter people have come up with a much better solution - Gravatar.com.

First create an account at Gravatar.com with a valid email, then log in, and pick an image on your hard drive and upload it. That will become your avatar icon, and whenever you make a comment on any WordPress blogs with the same email address that you registered at Gravatar.com, your icon will appear in that person’s blog comment section. Very cool!
