I was looking for a plugin to link internal pages. I tried several such as linkboss and others but they are very pricey for several websites. I was going to write my own when I came across this. While it's far from being as advanced as linkboss etc, it does a good job at adding links into each article. I wanted something that creates links using existing copy, but it does not do that. But hey, it works well enough so for the price I consider that my internal linking problem is solved.
