You are asking for clarifications. Good thing.

To be clear:

- I provide more types of lectures and you are sure all lectures of any type is downloaded (except Quizzes)

- Your course is uploaded to a dedicated server in a compressed file. So you know you can download it with lots of speed. You may download it anywhere like to your own host/server in just seconds.

- You can choose between qualities: 360p or 720p (Maybe someone can't afford much traffic on downloading)

- A guy who only needs one or two course(s) or wants to get courses not very often, pays less and goes economical.

- Even project files that is not supported in other services is provided in mine. (but as I stated in my post)
