Those of you who have signed up and are having problems changing your avatar, WordPress uses a system called Gravatar to display avatars for people based on their email address. You simply need to go to the Gravatar website http://en.gravatar.com and signup there using the same email address you’re signed up to 99 Adventures with and then upload your avatar. Any Gravatar enabled sites you then sign up to from now using the same email address will use your new “Gravatar”. Hope that helps!
