Each year, Moodle courses are refreshed to remove old student data and make the courses available for the next cohort of students.
The refresh has already taken place for the majority of courses, but those used for dissertation submission (typically those with course codes ending 499) are being refreshed on Tuesday 13th September.
If you are a student please ensure you have downloaded any materials from Moodle, and submitted your assignments, by the end of today, Monday 12th September.
Moodle will be unavailable for courses that this applies to all day tomorrow and current students will no longer have access to their 2015/16 courses after this date.
For further details about the Moodle Refresh, please see the LTI website.
