VSTS Rangers are a team of very active MVPs and other experts, such as Inner Circle partners, that are dedicated to improve the ease of use and adoption of Visual Studio Team System. Willy-Peter frequently blogs about the projects these guys are working and their progress.

Recently they released Quick Reference Guidance for Visual Studio 2010 on codeplex, which I think is very valuable. Go check it out:

“The Visual Studio 2010 Quick Reference Guidance consists of compact cheat sheets for Team Foundation Server (TFS) 2010 and Visual Studio (VS) 2010, addressing the core problem of teams in the field who are unaware of Visual Studio and Team Foundation Server capabilities or have little time to invest in detailed education.
The artifacts include an overview document and poster that allows you to quickly focus on individual areas like testing, by providing crisp and compact guidance sheets and quick reference posters. You can take these to your 5-min coffee break discussions or use them as a stepping stone to the more detailed and in-depth guidance you will find on MSDN.
The download package consist of three ZIP files containing a number of quick reference posters and quick reference sheets in XML Paper Specification (XPS) format:

• An overview of the guidance and focus areas, contained in one index table and overview quick reference poster.
• A collection of basic guidance sheets, focusing on the “what” are the key features and “why” to consider them.
• A set of documents and quick reference posters, supporting the basic guidance sheets.”
