Dev Notes

Requirements

• Facility staff can create an appointment at any time for any student and any mentor.

• Mentors can only create appointments for themselves, but any student.

• Appointments booked in this way bypass mentor availability, but a warning will be displayed if you are booking outside of the mentor's availability.

• Who booked an appointment and when should be logged with the appointment, to prevent abuse of this system.
