I have a client who requires a learning management system (LMS) integration for their online tutoring business. They require mainly cloud storage for course documents (pdf’s, powerpoints and short videos) as well as e-commerce functionality so prospective students can purchase course packages through the site. Another important thing they need is security logins for students, and perhaps a 2-step authentication login so students can’t share course content with others. Has anyone used or can recommend an affordable LMS/ application / plugin that can integrate?
