Teaching with Moodle

I'm eager to see if/how this parent role evolves, as we are looking to include our trainees' supervisors in our courses (we do professional development for nonprofit lawyers). The needs are a little different, however: we may not want supervisors to have access to participants' discussions, etc. In fact, we've been doing OK just creating a separate group for them. But there may be overlapping features such as a weekly newsletter (which we've done via email).
