How do I change my name in my email account?

I keep trying to change it, but whenever I go into the account information or whatever, it says that I have the right name, the new one. But whenever I send someone an email, it shows the wrong name.





Am I doing something wrong? How do I change this?

First, in looking for it, it told me I had to be using the Yahoo Classic interface.





Options, Switch to Yahoo Mail Classic, Options, Mail Options, General Preferences, and "From Name:" under Name and Email.





I had trouble finding it until I switched to classic. YOu can always go back to the new format after you change.
