It would be nice on the instructor descriptions if you could contact the instructor either only through email or by providing a telephone number to make sure that time frames work with the instructor as well as for the student

In the previous system we had the opportunity to contact instructors and members using anonymous email addresses. It would be good if such a facility were re-introduced. For example, asking for a plane to be tanked up or left empty etc.; ask if an article had been found in a plane.
