We're using Moodle 2.2.4
In Assignment settings, the "Allow Notes" is set to "Yes" and "Email Alerts to Teachers" is also set to "Yes".
In a foreign language course a student having a Macintosh edits and adds text to the assignment's Notes.
The teacher should receive an email notification of the submission, just as they do when files are submitted.
Our teacher is not receiving notifications of these submissions.
