Update: May 2016 this service appears to be offline. 

eDhii is a service that allows you to create or take self-study courses online. eDhii course creators can offer their content for free or charge a fee for their course content. Course creators only pay a fee if they choose to charge for their course’s content. Course content can include text, images, and videos. People in search of a lesson or course can search eDhii’s listing of courses and lessons by topic.

Applications for Education
eDhii doesn’t appear to offer a good way for course creators to “grade” assignments or to have students submit assignments. That said, it could be a good place to find a course or lesson for informal online learning.
