… you get what some people are calling a "Blogcast". Eileen Brown has posted a couple of short video clips blogcasts showcasing a specific feature on Exchange, one on Smartphone with Exchange and one on the Recovery Storage Group in Exchange 2003.
Let us know if you like this format or what you think about it, by posting comments here!
EDIT: Seeing that there were great comments on this, I wanted to let you know - Eileen posted yet another Blogcast today, on Exchange 2003 Deployment tools. Enjoy, and thanks to Robert for mentioning it!
