I just found the FAQs on Games Workshop's site, instead of the Black Library site. I'm not sure when this changed, but here's a link for speedy reference:

Or you can search for FAQ in the "Product Search" window.''
Orks, Dark Eldar and Space Wolves got a couple little updates.
I like the 'Download All' button but it would be nice if there was a single PDF document that contains everything.
