I'm sorry if I didn't make things clear:
- yes, a professor for a class can manage the folders for that class using the web interface
- a site wide admin can use the APM web interface to change the parameter for default folders created at class creation time. This can be changed after installation, too, it just won't affect the classes that have already been created.
- the goal is definitely to make this as flexible as possible. Our focus has been a lean, mean, massively configurable basic framework.
