At present, only an administrator can reset students passwords. What would be good is if teachers could gain this permission, and only this permission so that they can reset the passwords of students in their classes. This would take away a huge burden from the system admin. I know that there is a reset password procedure but not all students, and in particularly the early year ones, have e-mail addresses

It might be useful if the system administrator could choose which, out of all the admin functions could be passed down to other members of staff. You may want to not have this functionality for core items that would cause chaos.
