AJAX Security
Just about every time I do an ASP.NET AJAX presentation, someone asks me about some question about AJAX security. I always start of by saying, "I'm not an AJAX security expert, but I will do my best to answer your specifc questions..." Well, thanks to Joe Stagner, there are a bunch of upcoming AJAX security talks as part of the Live From Redmond series. They're on my calendar!
