How to change nick name in chat rooms?

How do i change the way my name is seen in chat rooms and on yahoo messenger?

• I initially used my sign in name for yahoo chat and messenger but now i want to change it to something else.

• Answer:

  If you are seeing your First and Last name in your Instant Message (IM) box, you probably signed up for a Yahoo! Messenger Account using your First/Last name. They will show in the IM window when you send an IM or receive an IM from another user, unless you change it. That does not mean the other person you are chatting with can see your First/Last name. Your Contact Details must be sent to them. If you have not sent your Contact Details to the other person you are IMing with, they will see your Yahoo! Account Name (or Nickname) and not your First/Last Name. Most users are uncomfortable having their First/Last Name show, even only to themselves (very wise of the user) and want to delete or change their First/Last name. Log into Yahoo! Messenger. Click on Messenger. Click on My Contact Details. If you want to have your First Name only, delete your Last name. 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. If you want only your Account ID to show, leave all fields blank. Always click Apply and OK when making any changes. If you have previously sent your Contact Details to the other person, they will need to delete you from their list and re-add you in order for you name to change on their list.
