When that urge hits you, don’t be caught unprepared. Make sure your gravatar is ready.
What the heck is a gravatar? From the gravatar.com website: “A gravatar, or globally recognized avatar, is quite simply an avatar image that follows you from weblog to weblog appearing beside your name when you comment on gravatar enabled sites. Avatars help identify your posts on web forums, so why not on weblogs?” Your gravatar is tied to the email address you provide when commenting.
Sign up is easy. All you need is an email address and password. Once your account is active, you can setup multiple
personalities email addresses and a different image for each.
