Have you ever wanted to have cool icons for your email address to use in forums and such? Well, this is the place to do it. They will generate your icon based upon your email provider. I gave examples of GMail.com and Live.com above but there is a large list of providers that they have.
Not only do they give you the image but they will also host it! They give you a URL that you can copy and paste wherever you would like the image to appear. This is quite a clever idea!
