My program made a big jump up to Moodle 2.7 over the summer and there have been some bid headaches around grading.
We used AJAX successfully last year and anytime you clicked a link to an assignment you had the option to REVERT TO DRAFT, which allowed students to revise and resubmit.
I don't see that option anymore, which coupled with trying to manage resubmissions in general, has forced me to set all assignments to perpetually allow updates.
Am I missing something? Is Revert to Draft still an option from a quick grade screen generated in AJAX or the system in general?
