How do I get a new screen name for yahoo messenger?

On my yahoo messenger my whole name is up there how can i get it not to show and just show my screen name?

• Answer:

     At the top of your main Messenger window click "Messenger" then "My Contact Details". Yahoo! first checks the "Nickname" field then moves to your full name if there is no nickname supplied, so edit your name and/or be sure you have something in the Nickname box then click "Save & Close".    Pay close attention to the information which appears in the option windows of Add Friend requests. It will send whatever information you have entered in the Nickname field, or the Name field if your Nickname is blank. On one of the steps in the "Add Friend" process, you will see the name you are sending them, and a "Change" button to allow you to change it.    Please remember that once 4 hours have elapsed since you've asked your question you are able to select a Best Answer. If any response you receive to any question satisfactorily resolves your issue please select it as Best Answer instead of allowing your question to go to voting. This adds helpful information to the database which may later assist another user and returns three of the five points you spent to ask this question. It also removes the potential for vote fraud.
