The module uses capabilities to control who can collect stamps and give stamps. Therefore, student can be allowed to give stamps to other students, the stamps may be given to teachers etc. Teachers can setup the module to show all stamps to all students, to show stamps only to the individual student to whom it was awarded or to hide stamps completely.
