We are thinking of modifying Moodle so that assessments such as assignments or quizzess can be set to a duration instaed of fixed dates. Our students can enter a course at any time, but they have to complete the course in a set amount of time. We therefore want to set deadlines for each student in a course based on their course start date and then the time after course start date assigned to an activity (and also to the course end date).
Is there anyone else interested in this?
