Dan Clausen from the Oklahoma City .NET Users Group presented DotNetNuke Development. I have done a few of those presentations myself so it was good to be able to sit on the other side of the table for once :-)
Now that I am SharePointing pretty exclusively, I had forgotten how much I loved being involved with the DNN community. I hope the SharePoint community begins to get some grass roots communities (like this web site ;-) ) to start building modules for SharePoint like they do for DNN.
If you want more DNN info, check out www.dotnetnuke.com or www.asp.net/forums.
Enjoy !
