I just signed up for a free ASP.NET 2.0 webcast series.  I've already seen 2.0 in action a dozen times, and played with it a little.  But I figure this will be really useful this time since I'm a week or two away from implementing a new website using 2.0 for the first time.  Plus there's some great swag for watching: Visual Studio 2005, a book, hosting and more.
