Here's my article on SSO. Now I have been a huge DotNetRocks fan forever. I love this show and their others (Mondays and Hanselminutes). I actually just created an application that crawls their sites for new torrents and downloads them. Might be posting that soon as I know a lot of developers that don't want to try to find all the old shows. Also if your a big torrent fan, like I am, get your hands on uTorrent, one of the first torrent clients built in C#. (gotta love it)
