A notification option has been added so that students can send an optional notification to instructors when they upload a file to their dropbox. It appears that the notification is a 'high' priority notification since the intsturctor receives it regardless of their resources notification setting.
We should have a notification preferences setting for dropbox notifications.
Student notifications should be low, so that instructors can control how they receive them (students don't get to pick and can't send high to force their notifications on the instructor).
Instructor notifications should have the priority dropdown for their notifications - so that they can send high or low notifications to students.
The instructor should have an options page where the ability of students to even send a notification can be controlled. If off, then the option doesn't appear to students.
Alternately, on the options page, there could be control as to how the instructor controls/receives notifications similar to what the assignment tool does, where there are radio buttons for
Do not send me notification emails for any student submissions
Send me a notification email for each student submission
Send me one email per day summarizing notifications for student submissions
