If you comment regularly, I highly recommend that you get yourself a Gravatar — a “globally recognized avatar.” This is a small image that you choose to represent you when you make comments on any blog or in a Forum. The software sees where you post your email address (required by most blogs) and then serves up the gravatar you have chosen. Here’s the website, it’s free, and pretty easy. Remember at the end to “confirm” the image that you have selected. If you are at a loss for an avatar – you can go to this site and create a Mad Men character that looks like you.
