How do you change the name that is shown to others on Yahoo mail beta?

Years ago, I made up a fake name to trick my friends. But I want to change my name back to my real one. But on Beta, I change the name, but it's not changing on the outgoing mailsHow do you change the name that is shown to others on Yahoo mail beta?You should have changed it in the settings area. It is supposed to take 24 hrs. to change that, which is pretty sad, I know. Also, if you have cleared the name area, it will display only your adress.
