Microsoft have a new site where you can submit your ideas and feedback for ongoing development of the Windows Server product line.

Help us improve Windows Server by providing us with your suggestions and ideas. All feedback
submitted will be sent to the Windows Server Development Team for review and analysis. Your ideas
can impact Windows Server in many ways, and might even be incorporated into new Service Packs,
Feature Packs, or the next Windows Server release.

After completing this page, you can opt to participate in a variety of activities such as
online surveys about Longhorn Server and volunteering for beta testing.
