In the course element "course members" there are two email forms:
- The direct contact mail right next to the user name (envelope symbol)
- The mail form to send mail to multiple users (using the mail button at the top right corner)
In both cases, the mail that is sent to the user does not contain any clue about the course origin. It would help to have the course name and the direct link to the course.
To make it flexible, the course title and link should be added to the body form element so the sender can still remove it if not desired.
