Questions? MSDN has answers.

A great place to get your TFS questions answered are the MSDN forums.  Microsoft and community TFS experts monitor the forums constantly, and usually are able to begin providing help in about a day.  To start getting answers, just post a new thread describing your issue, include any applicable error messages, and if possible, the steps to reproduce the error.  You can also browse previously answered threads to see how others experiencing problems with TFS were able to resolve their issues.
