I’ve enabled Gravitars for this site, for those that are unfamiliar, it allows you to have a Globally Recognized Avatar.
Totally free, very easy to use, just a cute little thing to give us that extra neet factor. http://www.gravatar.com
Just give them your email address, give them a pic to use, and anytime you leave comments on an enabled site, your chosen image will be your avatar pic. Wordpress has this enabled integrally, so it should show up probably more than you might realize.
