We have relaunched the Microsoft .COM SharePoint Server 2007 product web site with a new look and a lot more content! Check it out here: www.microsoft.com/SharePoint. This is version 1.0 of the site and we will continue to make updates and improvements to it in the next few months.
– Here are some of the key page redirects
o www.microsoft.com/SharePoint/Collaboration (and /Collab works too)
o www.microsoft.com/SharePoint/upgrading (includes some Notes Compete content)
