Cloud9 Education - Ability to lock accounts for restrictive access



Hi, I am a Computer Science teacher based in the UK. I use Cloud9 Education accounts to teach programming to all of my students.
As part of the official GCSE course, students are restricted from accessing their programming projects outside of the specified times. Is there an ability to temporarily lock students accounts, so they cannot log-in at home and have access to their source code.

If we are unable to lock the student’s accounts when not needed, we will not be able to use Cloud9 for Education, and we will have to resort to another Web IDE, which is far more expensive.

Many thanks,
