EduNuke is a new site for educators and developers interested in extending PostNuke (the collaborative weblog tool that is powering Kairosnews) for educational purposes. Their vision:

Extend, focus, and shape the ideas and efforts of PostNuke (PN) to meet the needs of the fast-paced world of technology, teaching and learning. We welcome developers, designers, and educators who would like to contribute. We are not a fork of PN and have a close relationship with the team of core developers at PN. Again, our goal is to create a "flavor" of PN focusing on the unique needs of the elearning/distance education markets.
