The actual security guide pointed to resides at ZDNet, but this site lists the four parts together (and the ZDNet navigation is not exactly clear). Navigation through the checklist is not completely obvious either. You can go through by clicking on arrow icons (<>) at the upper right hand corner of the images (which may be hard to find because the images can be fairly busy), or by clicking on individual pictures below the image and text. (Clicking the arrow icons down there only moves the pictures back and forth, without moving you through the checklist.)
However, once you master the oddities, the checklist can be quite helpful. It is fairly complete, and, although the text instructions on how to find the items can be difficult, the fact that the image displays the page in question, and the red numbers point out what you are supposed to choose, allows you to check that you are, in fact, on the right page. The instructions may seem simplistic if you have been using Facebook for a while, but they will be great for a newcomer, and even the "expert" will likely find a setting they didn't know about.
