Edu20.org allows anyone to develop an online classroom for anytime anywhere learning.
In the example below you can see that immediately upon creating a class, the "teacher" is given multiple pages with which to work. Including resources, lessons, a calendar, a gradebook, a forum, a chat, a wiki, and the list just goes on.

In a future episode of Dr. Disk at Work, I will be setting up a "Classroom" that I will be integrating with Certification Central (one of my many projects). This wll be a guided tour through the entire process. Please check back to see when the episode will be scheduled.
