Technically Forum 18 are spammers as I didn't ask to be put on their mailing list but now and then they send interesting stories.

The Old Believers historically are a good example of being orthodox but crazy - a point taken too far, even though to be fair Patriarch Nikon was hamhanded in the way he tried to impose the very slight changes to the Russian Orthodox services in the 1600s.
