How can i change the settings not to show my name?

How do i change my settings on messenger so that when i send an im my first and last name do not show?

• Even though it shows my alias in "send as", once the actual message is sent, my first and last name show up on the conversation screen.

• Answer:

  To edit your name as it appears in an IM box... 1). Log into Yahoo! Messenger. 2). Click on Messenger. 3). 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. 4). Always click Apply and OK when making any changes. For addition explanation and information go to http://www.chatauthority.com/changename
