Messages are generated internally through the Well Beyond Care notification system. If you have any pending messages to be read, you will see a heart with a number inside it on the Messages icon on your status bar. The number indicates how many new or unread messages you have. In order to read a message, click the Message icon (an envelope). You will then see a listing of your messages. Unread messages are highlighted. Just click on the message you are interesting in viewing and a dialog box will open up displaying the message. You can reply to that message in that dialog box.
