I'm posting this because I've been looking for this site forever and no one I asked knew where it was. I hope it can assist someone else wanting to submit ideas to MS about SQL Server.
Question: I have an idea for a nifty new feature (or a fix) that I think Microsoft should include in its next rendition of SQL Server or next Service Pack. How do I get that information to them?
Answer: Submit your ideas, with an explanation of the enhancement's benefits (including how users other than yourself could benefit) at the below webpage. You must have a Windows Live account (also known as Windows Passport account) before you can submit feedback.
