For example, John Smith logs into this site using his Facebook username and password and he submits a translation of a paragraph. This site records the translation as submitted by someone with the unique Facebook id of 123456789. The translation history of this paragraph will show a small profile picture of John that points to <img src='http://graph.facebook.com/123456789/picture' />. If John sets his Facebook privacy settings to only allow his friends to see his profile picture and no one else, then when a friend logs into the site, this code will make his real-time profile picture appear. All others will see a profile picture as handled by Facebook. Names are similarly handled. We keep associate your Facebook ID with each translation that you submit in order to acknowledge your contribution and to allow others to contact you about your translation.
