You can even use Yahoo! Messenger’s availability status to set your account to invisible, making it appear you have signed off when you want to continue a conversation with a contact without someone else know you are online.
To access the Yahoo! Messenger availability status panel, first click “Messenger” on the top Yahoo! toolbar, then select “My Availability.”
