Team System how-to videos up on asp.net
There are some really sweet videos over on the asp.net site to help kick start users of VSTS. The videos are typically 8-10 minutes long and to-the-point. Very useful for those that are looking for quick starters or help with a specific scenario. Personally, I love these kind of videos as compared to the lengthy hour long tutorials and talks. Short and fast - gets me started right away.
Eric Lee gives a short intro to unit testing with VSTS as well as using code coverage inside of VS. There are some good videos on load testing and web application perf profiling by Chris Menegay as well. Check out the videos and let us know if you want any specific videos up!
