Root and Source points to a new (newer than what I knew) Brahmo Samaj website. The Brahmo Samaj is the analog in Hinduism to classic Unitarianism for Christianity. (Thus the categorization.)
Interesting people and I'm glad to see they have an expanded web presence.
2008 July 4. This site is gone, but it has been replaced with a Google Pages site, which seems right too. There is a Wikipedia article -- with a lively discussion about its merits.
