Tagging someone in a sentence on Facebook is a great way to let others know that you and the friend are doing the same activity. It's also a good way to let the person you tag know that the message you are typing is about them. Facebook only allows you to tag people who have confirmed you as a friend. When you tag a friend, a hyperlink is created to the person's profile. You can tag someone's name in your status updates and comments.
Log in to your Facebook account with the registered e-mail address and password. Your news feed is displayed when you log in to your account.
