I just read over on Mitch's blog about some new features that are going to be included into the next release of TFS Power Tools. Each of these new features looks awesome, but one caught my eye in particular that I personally can't wait too see. that feature is the new Team Members folder. Not only will this allow you too visually see who is in your project team, but it will also provide integration with your *IM client for presence, notification and vital communication functionality.
I'm all for collaboration, and any tools that help me communicate better with team members is a win in my books.
