Unfortunately, they still haven't figured out the "next" button referencer yet for any of the in-house article webpages. Just scroll down and you see the page numbers listed after each of the page titles. For example, there are 2 pages to that article if you look at the bottom of the screen. Select the one that says "2 of 2".
It's probably just a problem with the template used for the pages but it is a little annoying since all of the articles use the same one.
