When working with a custom skin you may notice that the DotNetNuke RadEditor inherits the same background color or image as your web page.  This can make editing content very difficult.  With the latest version of DNN, it is very easy to fix this issue and set a white color, or any other custom color using css.

DotNetNuke has a new ability to show PopUp's much more easily!  You can make entire modules work in a single popup or extend module functionality and usability.

For a long time I have always used the Globals.NavigateUrl() method in DotNetNuke to create links in my custom modules.  I have recently converted to using the FriendlyUrl provider in DotNetNuke.  The big advantage for me was to create a custom page url for SEO purposes without hacking the DNN framework.  I wanted to get rid of the standard Default.aspx and also create urls that were more SEO friendly.
