The NAD adopted the wiki a few years ago and is now hosting it at
http://wiki.pathfindersonline.org - part of the reason we went that way was so that we could add material for the Friend/Companion/Explorer/etc classes. That material is more religious in nature, and so would be difficult to defend against the policies at Wikibooks.
This leads to two suggestions:
1) Use the NAD site instead of the Wikibooks site, because new honors and features have been added at the NAD site, and the Wikibooks material has essentially been abandoned. Since the wiki is hosted by the NAD now, we are able to show the honor patches, and install various extensions to the software to make it more useful for our material (that required community consensus at Wikibooks, and they were usually quite resistant to such proposals).
2) You should upload your powerpoints to the NAD site linked above and start adding material to the wiki there so that it can get a wider audience. Don't worry about whether or not you know wiki syntax - just add the material, and we will gladly fix up the formatting for you.
