Sure. I can make “administrator” any name entered, by clicking the pencil symbol next to its name and then the “administrator options” button that appears on the right. At that point I can decide, by checking the “Manager” box, to let him manage only the classes and notifications on the bulletin board or, by ticking the “Personal Trainer” box, let him manage only the workout cards or, by ticking both, give him the possibility of managing the entire BookyWay system. At that point that person will be able to enter (as well as from the app) into the system from any computer with his email and his pw.
