How to change my name to a nickname on Yahoo messenger?

When in messenger my contacts are seeing my real name instead of my yahoo nickname. How do I change this?

• I have tried to change it in contact details and preferences but I can't find it. Please direct me as to how to remove my real name and show only my yahoo ID.

• Answer:

  If you used your First and Last name when you signed up for a Yahoo! Messenger Account, your First and Last name will show in the Instant Message (IM) window when you send or receive an IM from another user, unless you change it. To delete/change your name.... · Log into Yahoo! Messenger. · Click on Messenger. · Click on My Contact Details. o If you want to have your First Name only, delete your Last name. o If you want to use the Nickname field, delete your First and Last name and enter the name you would like to see in the IM box in the Nickname field. o If you want only your Account ID to show, leave all fields blank. Click ‘Save & Close’. Your Old Name Setting Will Continue To Show For Anyone who already added your older name information to their Messenger List or Address Book will continue to display that information in their Messenger Lists and Address Books If you want them to see your ID differently, you should request that they remove you from their Messenger Lists and/or Address Books, and then Add you again as a new contact with your new information.
