Thanks for your questions about how to create an online course, - replies to which I've added to WUaS's FAQs - http://worlduniversity.

'''How I can create an online course?'''
a. Build it gradually. For example, simply start teaching to your web camera for 3 minutes, mention a book, then build a syllabus and a series of lectures, and invite potential learners to meet in a Google + Hangout, for example.
b. Use some of this course making software using, for example, Google's course-builder -https://code.google.com/p/
course-builder/ - which is available here at WUaS's Course Management Systems - http://worlduniversity.wikia. com/wiki/Educational_Software# Course_Management_Systems- with other course-making software, or start one on a free wiki, which software is also accessible on this page.
c. For a MIT OCW-centric course, that might eventually be taught for credit on the degree side of WUaS, use a MIT OCW course as a model, and then construct the course on a web page, or using the above software.
I'll reply to your other questions later, but Google's course-builder is a great example (thanks to Peter Norvig) of the direction WUaS would like to move in for organizing all of this WUaS material.
People teaching to and learning from each other is what WUaS is significantly about, which your questions point to! Thanks!
