Microsoft has created a new site on Technet for their Beta programs called Technet Beta Central. If you are a Technet subscriber, you are auto enrolled. Otherwise, you need a passport account to associate to the beta programs. It looks like you will be subcribed to their TechNet Flash IT newsletter. Right now the betas on the site are Vista, Office 2007, and Exchange 2007. The enrollment states it will take a few weeks to start receiving information.
PointBridge has access to the betas as well and will be posting bits to the file shares as they become available. However, this gives you an opportunity to stay informed on a personal basis. May 22 is the release of Office 2007 Beta 2. I expect everyone to be installing Outlook 2007. It rocks!
