A few folks have asked how to they can setup their avatars so it shows up in the comments. The current WordPress theme I’m using is integrated with Gravatar. You simply need to visit the site and create an account using the same email address that your using on this blog. A vast majority of sites use Gravatar so your avatar will also start showing up in those sites as well.
You can sign-up for an account at this URL; http://en.gravatar.com/site/signup
Cheers!
