Last year after Tech Ed 2005, I wrote a little app in .Net 1.1 that allowed me to track which sessions I watched on the DVDs. This year, I did it again and I have made it available to you via a ClickOnce app. Navigate to http://www.ksdynamics.com/others/teched2006dvd/ksdynamics-publish.htm.
I'll point out some things I learned later this week.
