This one is interesting. I signed up for a webinar on November 19 at 12 PM through Social Media Today called Socially Driven Collaboration: How Social Business is Changing the Role of Marketing and IT. I got the confirmation email and everything. (access code: 373-406-469) However I could not attend. As I understood though I thought that having registered for the webinar I would be allowed to access and archive of it, so I wasn't too concerned at the time. Well, I was wrong. So I did not attend a webinar through the semester. But if I had, this would have been the one.
