It the past when you wanted to log into facebook you had to type out your full email addy well that changed on friday. Now when you go to log in you can simply type in your vanity name. You know that name you picked a while back the facebook.com/XXVanity NameXX Now if you have a love affair with the @ you can still type in your email addy and it works the same. This is just a new feature that facebook has started (and its about time).

If you dont have a Vanity Name and what to get one check out this thread: Facebook username and if you have one that maybe you picked late one night and now HATE well you can change it - here is how: Do You Hate Your Facebook Name?
