If you’ve ever commented on a blog, you’ve probably seen that other people had cool icons associated with their usernames. Sometimes it’s their logo, sometimes it’s a personal photo, sometimes it’s their favorite catch phrase. No matter what it is, they’ve got a way to express themselves or incorporate some of their business’ branding into their online socializing, and you’re left out. Not cool!

In many cases, the secret is GRAvatar, or Globally Recognized Avatar. Gravatar is a centralized service that associates icons with email addresses, and it’s in use on literally millions of websites.

It’s really easy. Just visit http://en.gravatar.com/ and click “Get your Gravatar today.” Follow their simple steps, and you’ll be on the way to joining the cool kids’ club with a personalized icon that can follow you nearly anywhere online.
