I have been using Moodle at Vancouver Island University in Canada, when having to submit an assignment that has to be written in Moodle the system has the problem of logging you out after awhile and if you forgot or did not realize that you must save your work then all your work is lost when you log back on.
I suggest that an autosave function be added to Moodle that would save your work every 1 minute or even every few seconds, this would remove the danger of losing all your work. Even my professor who has a masters degree in management science lost some work because of this.
Thanks
