Cleaning up? Here’s how:
Right-click the friend or contact and select Delete. Then click Yes.
That’s it!
The contact will not be notified that they have been deleted. If you no longer want to receive messages from this person, click Messenger, then Preferences, and then from the list on the left, click Ignore List. Click Add, enter the person’s ID, then Ignore… and finally, OK. Ahhhh, peace and quiet. You can have a change of heart, too! Go back and remove the contact from your Ignore List anytime.
Note: When you remove someone from your Messenger List, you’ll also have the option to remove them from your address book.
