Hi Sharon,
I see that you are using Moodle 3.0.6, so you might be interested to know that Moodle 3.2 is due for release soon and has improved, in my opinion, the Moodle internal message system. Instead of the pop-up at the bottom right, that is very easy to overlook, you now get a red square with white text indicator at the top right corner of the page by the user name, that is persistent no matter where you navigate to in Moodle, until you click on it.
