What are  Volunteer hours log and how to enable or disable that

It is just an hour's log for the students and the tutors and nothing else. You can also disable that

So tutors can add hours and images for each log etc

Students can approve or decline, a tutor can send reminders for approval to the parent email address

Both users can download the hours log submissions in the PDF format
