I received an email today about a new project that is out on CodePlex that focuses on TFS/VSTS. I figured it was worth a look and boy was it. This is a project that was created by the Patterns and Practices group at MS. There is so much really good information there. I would highly suggest that if you have questions and or interest in Team System, you head over here and dig through the information. I am sure that you will find answers to many of the questions that you have. I personally subscribed to the RSS feed to keep me updated and to have that information handy at all times.
