Team (class) workspaces, are they visible to outsiders?


I am about to start a class which I would like to perform assignments each on their own workspace and I will have a script for them to submit me their work.

Since we will hold many classes moving forward, I am worried about previous student’s workspaces being open for new students to read all the answers of the upcoming course.

How should I go about managing their workspaces?

Advice would be appreciated, and if current features do not allow a good solution I would love suggestions on possible solutions we could ask of c9.
