Stealth settings allow you to appear online to some people and offline to others. A stealth setting of online or offline can be activated for an entire group or individual contacts. To set up stealth settings:
If a contact in your Messenger List appears in italics, you appear offline to that contact.
Note: If you sign in as Invisible, your former stealth settings are erased.
Where's the Contact Customer Care button? With so many improvements to Messenger since the version you're using (lots more features and reliability), we figured you're ready to move up. So get your upgrade and with the new version, rest assured if you have questions, you’ll find that friendly button on its help pages.
