Time based subscriptions

Hi James, Thanks for your quick response. I will try to answer your questions. 1/ The paying students would arrive directly through the e-commerce part of our website/Opigno. The non-paying students would arrive through requests from their company/employers which pay for their employees. We would therefore have to sign them up manually as billing and payment would be done separately in our accounting software and e-commerce is not involved. So we would be selling exactly the same thing to both but subscription and payment are done differently. 2/ I guess the group (class and included courses) are thus semi-private? 3/ Type of sessions: I am selling blended learning packages including face-to-face in-class with teacher (this is what I mean with "session") + on-line learning activities, between 2 sessions, which need to be tracked even so in order for the teacher to follow-up on work done by student. The way this would work on Opigno: I would create a CLASS/Group according to subject, which would include 2 courses (one for face2face lessons and one for on-line lessons). So to answer your question: I am selling an “Opigno CLASS” which includes 2 courses (face2face + e-learning). But you can consider the e-learning to be FREE as I will not be billing for connection time. I have no problem with this so far. But here comes the tricky part: My idea is to create an “all year round on-going” CLASS which would be running let’s say every Monday for 2 hours (e.g. 14.00 till 16.00 pm). I want students to be able to sign up, any time of the year, for 20 hours (10 sessions from the Monday they start). This means that within this same CLASS/GROUP, I would have students with different access/expiration dates to this class, depending on the day they subscribe and the Monday they start. Administrating manually each single user expiration date to that class would be a nightmare. Is there another way of doing it? I hope this helps? Best regards,
