I can see on the editor interface that there are not so many schools using the student site. I use this all the time with my students and its quite easy to set up.

• First Set the password for your students, you can have one per year if you want.
• Select the pages you want your students to view (not all pages are available but most are)
• Give the password to your students and get them to login. If they login through the teachers login they must select "student access".

We are working on several new features to make the students part even better so watch this space.
