In addition to the one-day technical overview of BizTalk that I have already mentioned, Microsoft is also sponsoring two 4-day Hands-On Lab sessions for BizTalk Server in the NorthWest.  One will be in Portland, Oregon (April 13-16), and one will be in Bellevue, Washington (May 17-20).  These are free events, targeted at developers and system architects.  Machines with configured Virtual PC environments will be provided, or you may bring your own machine that has Virtual PC installed, with enough room for the Virtual PC image. Please contact me if you are interested in attending, or register using the links below.

Portland (April 13-16)
Bellevue (May 17-20)
(apparently you can't register for Bellevue yet...  I'll update this one ASAP)
