As I was setting up a new fanpage for a client today I noticed that the username section in facebook now seems to have an option to allow you to change it. Something they said would not be available when they announced usernames in June.
When the usernames launched last month some people chose a name not necessarily related to their actual name and one they later regretted.
If you were in this group, you can fix it now. Simply go to your settings tab and under account settings you can go in and change your username.
My advice… choose wisely, especially if you have a business presence attached to your facebook profile.
