I want to advertise a couple of sites that can be used for submitting feedback and suggestions, or for filing bug reports for Microsoft products. These are:

The Microsoft Technical Forums at: http://forums.microsoft.com/MSDN/. The SQL Server Forums are at: http://forums.microsoft.com/MSDN/default.aspx?ForumGroupID=19&SiteID=1.

The Product Feedback Center at: https://connect.microsoft.com/default.aspx.

Update [2005/12/21]: Another useful link for reporting security vulnerabilities is: http://www.microsoft.com/technet/security/bulletin/alertus.aspx
