Finaly, Facebook allow user URL names. Starting at 12:01 a.m. EDT on Saturday, June 13, the Facebook will start allowing its users to identify themselves through a user name in addition to their real names on their profile pages. For example, you can switch from http://www.facebook.com/profile.php?id=5456874 to http://www.facebook.com/john.URL must be at least five characters long, and once you pick a name you cannot change it, so choose carefully.
