Instead if having to remember a lengthy Facebook URL such as http://www.facebook.com/home.php#/profile.php?id=531173044 you’ll soon be able to type in http://www.facebook.com/yournamehere and be taken directly to your Facebook page. That is assuming that you’re fast on the keyboards and sign in at the stroke of midnight Saturday June 13, 2009. That’s when Facebook will allow you to request your own free personalized address. It’s first come first served for names – so don’t delay signing up. And be sure to chose wisely because once chosen the vanity name cannot be changed or assigned to someone else.
Facebook usernames will be available in basic text forms, and you can only choose a single username for your profile and for each of the Pages that you administer. Your username must be at least five characters in length and only include alphanumeric characters (A-Z, 0-9), or a period or full stop (“.”). While usernames are currently available only for Romanized text, we’re looking at how we might support non-Romanized characters in the future.
Think carefully about the username you choose. Once it’s been selected, you won’t be able to change or transfer it. If you signed up for a Facebook Page after May 31 or a user profile after today at 3 p.m. EDT, you may not be able to sign up for a username immediately because of steps we’ve taken to prevent abuse or “squatting” on names.
