Would you please help me locate the web address of this innovative, cultural creative adult learning school that teaches online university-level classes for self-knowledge?

Hope someone can help me find this…this school had classes that you could take online, not for credit, but just for self-knowledge. Lots of the instructors were from top universities and most of the courses were in specialized subjects….things you might not be able to find in the regular curriculum at a university. Many of the instructors were experts in their fields or noted writers and authors.

The classes were amazingly interesting and diverse….from art history to ancient archaeology (but with a twist, much more specialized and/or unusual.) It was a bit like the “New School” but online.

I lost the web address…and I hope someone out there knows the organization I am talking about…thanks so much!
