A best-of-breed up-and-coming framework (Score 3, Interesting)

Disclaimer: I am not connected in any way with MIT (I'm from Univ. of Texas at Austin). MIT (along with others) has an excellent project called dotlrn:

MIT Intellectual Commons (collection of related e-learning initiatives including dotlrn): http://web.mit.edu/cet/strategy/commons.html

What is .LRN? (from www.dotlrn.org ):

-A fully open source eLearning platform.

-A portal framework and integrated application suite to support course management and online communities.

-A scalable, secure, and enterprise-ready eLearning platform that can be deployed readily by small and large organizations.

-A modular architecture to permit flexibility and to drive innovation.

-A set of best practices in online learning shared in the form of source code.

The dotlrn project page has documentation, news, forums... It is hosted on the www.openacs.org site, which is the parent web framework upon which dotlrn is based. Besides the above, the framework has a rich architecture for managing permissions, users, groups, content management, course management, forums, email, and more.
