A gravatar is that little picture you see with some folks’ comments — a photo, a cartoon, or what have you. If you don’t have one, the site will use the "VARbuzz V” instead:
So, I hear you ask, how do I go about getting one of these, lest people think I look like a talk bubble? Here’s how:
Find the picture you want to use. It’s going to be A) shrunk and B) cropped to be a square, so keep that in mind. Want a cartoon instead? Go to WeeWorld and create one, then save it to your hard drive. (If you don’t know how, um, ask someone.) You can also go to the South Park Studio and create a South Park-like character.
However you choose/create the pic you want to use, you need to go to the Gravtar site and enter your e-mail address. You’ll get a confirmation, and then you’ll upload the image you’ve chosen to that site. You’ll have a chance to crop it there:

You can have multiple e-mail addresses, and different gravatars assigned to them — professional and personal, for example. And then your beautiful mug will appear with all your comments here and at any other WordPress-powered site where you’ve given your e-mail address.
