Quakerpedia

Quakerpedia is a wiki about Quakers, aka the Religious Society of Friends (a 17th-century English religious movement) and everything descended from or related to them.

It was founded in fall of 2006 by Zach A, and runs on MediaWiki. As of spring 2007 it is still in "alpha" stage with about 70 articles. All textual contributions are released into the public domain.

As of January 2008, Quakerpedia appears to have been shut down.
