Wikitruth.info seems to be slashdotted, but according to the Google cache, http://72.14.203.104/search?q=cache: 8yjjGVPUOb0J:www.wikitruth.info/ or http://tinyurl.com/otg6n , the Wikitruth wiki is not editable, for our own good.
In its words: "We want you to read this website, not be locked in a full-on piss-battle over changing varying articles to reflect the whims and madness of a thousand people. Wikis do work, make no mistake, but they ultimately only work when you have a small amount of people doing the editing. Sure, it progresses a little slower... but it progresses."
