I've completed documenting all of the Standard Reports in SQL Server Management Studio. You can get to them from the tags, but I thought I would post a list of them all here with the links.
I hope that you've been able to put some of this information into use in your organization. A lot of work went into creating and surfacing these reports, and we think they can really help you make your day more productive.
I'd also love to hear if you've created your own reports, and how you're using them. If you're willing, you can post them on CodePlex, and leave a link here.
