Office 12 Beta 2 now available
If you are part of the Office 12, you might have already received the email detailing that Office 12 is out at
http://beta.microsoft.com. On the other hand, it is also available on MSDN if you have Universal Subscription. If you don't have either, seems like Microsoft has opened the beta to more people, and you can get the beta 2 (which will run till Jan 07)
from here.
