GW have asked us to remove them in anticipation of the new rules being released, so that players who are new to the game do not get confused.
The CRP will continue to be used at NAF tournaments until further notice, but the document will be removed from thenaf.net at the end of June 2016, as it is a GW document. Therefore please do download it for personal use before then.
This is a little worrying about places like Yaktribe. Nothing really dies or goes away on the internet, but having a central hub for the rules and for community-driven improvements is much more convenient than trawling Mega or 4chan.
