@flauwy Thank you for your interest, here is the answers to your questions.

1.  The platform will be on steemdevelopers.io but it will connect to steemit 
2.  Posts for educators = course material (tests, assignments, projects) , class interaction on posts
3. Yes, each course that an educator creates will be the standard course outline for that educator's field of expertise. We wont have you guys creating new curriculum every week.

So 150 SBD (max) per course you guys put together, every time you get a round of students. Plus payouts on your actual course material.

This 150 SBD also is what we are offering now, we are just getting off of the ground and trying to grow and build with educators. If you would like to become one please feel free to email us @ steemdevelopers@gmail.com
