My usename is set to "admin" and I want it to be "luke". My bosse's username is his whole name and I just want it to be his first name. It won't let me change either of them. I could deal with the admin one, but he doesn't want to type in his whole name every time he logs in (it got changed to that somehow when we imported from an old wordpress blog).
If I were to change the username directly in the database, would that mess anything up?
