If you downloaded the VPC image version of Visual Studio 2008 beta 2, make sure to back-up your data and move anything off of the Team Foundation Server before November 1, 2007. I was just informed that the images will be time bombing on November 1 2007 rather than the originally intended March 15, 2008 date. If you don't download it now, you may not be able to retrieve your projects. More information is available at the VS 2008 beta 2 download site. If you installed the stand-alone version, you should be ok.
