Public ClassRoom for CheckiO users

As you probably know, we are relaunching CheckiO ClassRoom, which has many analytics tools. The main goal is to run a private class. But would you be interested in creating a public class on CheckiO?

The idea is very simple - any CheckiO user can request to join your class, and if you have the request approved you see his/her progress in your ClassRoom Manager.

What do you think? Is it a good idea? Bad idea? Doesn't make any sense?

Thank you and happy holidays.
