Is there an issue with Facebook today?

To talk to someone on Yahoo, you can use Yahoo Mail or Yahoo Messenger (if it’s still active). For Yahoo Mail, compose a new email and enter the person’s email address. If using Yahoo Messenger, add the contact to your list and start a chat. Make sure the recipient also uses Yahoo for seamless communication.
