Hi Tiarra! Welcome to the forums!
BB Messenger is primarily used to talk with others who also have a BlackBerry. You typically add people using a PIN number. Your PIN number can be found be pressing Menu>Options>Status. You can add people via email address but it doesn't work that well.
You should get some of your friends PIN numbers and send them an invite.
