• Answer:

  on your menu bar click "messenger" you'll then want to go down to "preferences" and click on that in the new window, click on the "appearance" tab on the left (its towards the top) once you've done that, you'll want to go to the options towards the bottom of appearance under "for each contact on the messenger list, show their:" you'll want to choose "nickname or first and last name"
