How do I change my BuzzFeed.com username?
While you can change how your username appears on the site (see 2 questions up from here), you cannot change your username. BuzzFeed is all about getting posts linked to from all over the web so we are very careful not to ever break links. Since your username is your url for all your posts (http://buzzfeed.com/username/post-name), doing so would break all links to your existing posts. That would make everyone sad. If you really, really need a different user name, you can always just create a new account.
