Josh's mirror of Harry Potter and the Methods of Rationality has been redesigned by Lightwave (who also did IntelligenceExplosion.com, Friendly-AI.com, and lukeprog.com), and it is now located at a simpler URL: HPMoR.com. Thanks also to Louie who put together this "facelift" project.
There is a bad link at External Links --> Book-style PDF
I've commented out the link, because the PDF seems to have gone away and the copy of it I have only goes up to chapter 72. I've got email out to its creator asking if he'd like me to host it or transfer the project files so I can keep it up to date.
