The openstreetmap.org website supports the display of [http://gravatar.com/ Gravatars], these are retrieved from gravatar.com by generating a globally unique key from your e-mail address. Our website software will check on the initial signup and on every email address change if you have a Gravatar for the new address and start displaying it if one exists. You can stop this behaviour by explicitly turning Gravatar support off in your account settings. You should be aware that, if a Gravatar is displayed, the key can be used to track your account over any website that has Gravatar support.
