Putting an Outline on your DotNetNuke Site
This is a very powerful combination because it makes it easy for a site manager to publish OPML based information without using only the DNN site management tools and Dave's Outliner.
I added an XML/XSL module to a DotNetNuke site, used my OPML as the XML, and used this XSL, this CSS, and this JavaScript (slightly modified from here) to create this page.
