Wait a minute wait a minute, so its not a editable wiki? You cant drop a single line?

No, your not understanding. The wikibook is run by Evan Carroll, and NOT by the Moose core development team. Evan has said (see above) that he thinks it still has value, while a fair portion of the core Moose contributors think that he has gotten a number of things wrong and/or incomplete. This has been an ongoing debate since Evan started the wikibook, it is not worth discussing the politics and assorted bullsh*t that has gone on for years. And it is certainly not worth playing wiki-editing games with Evan to try and put a disclaimer on the front page.

In short, it exists, but it is not "official" in any way, shape or form and it is not recommended by the authors and developers of Moose. You are free to read it (and edit it) all you want, but you should take it with a very VERY large grain of salt.
