in a course. Firstly, the course settings page now allows the teachers
to specify the word they want to use in place of "teachers" and "students"
as well as "teacher" and "student". Secondly, a new teacher admin tool
allows any teacher to modify the order and displayed role of teachers
in that course. This affects the display on the course listings, the
participants page and so on.
Sections covers "weeks", "topics" and anything else that may come along.
Note, again, some databases have changed esp course_weeks -> course_sections
and several fields called "week" are now "section. Also course no longer
has an enddate, but instead has a numsections field.
