When I go to a list of the course participants to send a message, say, it lists 20 students (in a class of 24) which an easily missed 'show all 24' link at the bottom of the page.
I can't find anywhere to change this setting to make it show all students by default. There is a similar 'per page' setting for viewing grades but it doesn't affect this page.
How do I change this in Moodle 2.7?
