The big answer here is that we are discussing this now. We may be putting some of it in the subscriptions. The snag is that the content in these classes is REALLY meant to be watched, then worked on with a dialog between the instructor and the student and we want to push that. Then, the student has to be comfortable with their work and crits being shared with everyone who has a subscription. So far many of the students prefer a safe place to show their work without the world seeing it (Which is certainly understandable).
Classes also have resources that need to be downloaded like pdfs, etc. and such a massive amount of time and energy goes into the creation of it that we want to keep the interactive classes as a unique experience for when the student is ready to take them and then really dive in.
But like I said, we are exploring the pros and cons now as we build out the classes, so we will see how it goes.
