Really it will be an interesting meeting, Trika  just posted an announcement about Live Meeting to Introduce Exchange 2007 Certifications

Rob Linsky (he's Microsoft Learning's cert product manager, you've probably heard him speak at an event or one of our other meetings...) will talk about the new exams, associated training, and implications for people planning to work with Exchange 2007 or who hold an MCSA: Messaging or MCSE: Messaging certification. As usual, we'll have 2 meetings with the same content to make it easier for people to attend worldwide and ask questions.

Register for February 15, 2007, 7:30 AM PST (What time is this in my region?)
