We do have a courses platform, but it is different from the other platforms. Leanpub courses are written in plain text, in Markua (here's the manual: https://leanpub.com/markua/read).
Here is a free example we use to introduce people to the concept, if you're interested: https://leanpub.com/c/creating-leanpub-courses.
Also, here is a course Track you can try for free, if you slide the pricing slider all the way to the left, when you get it: https://leanpub.com/universities/set/jhu/cloud-based-data-science.
