Can this vshare script be set that only admin can add members and it locked out to public view until they are logged in?

We wanted to have something to store our school lessons video but we don't want it to be viewable to public and create an account for each student to log in to be able to view the videos and also keep track on which videos the student have already viewed or not viewed yet.

Is this possible on vshare script?

Thank you
Bill
