One of the features here at DotNetNukeBlogs.com will be to highlight interesting DNN sites that we come across. The first one I want to bring focus to was brought to my attention today by my boss.
Take a look at http://bugnetproject.com/
At first you might think that it is not a DNN site, it looks like another software package that used to be "open source" but never really was.
Great implementation!
