The Seattle Team System Users Group meets on the last Wednesday of each month. The meetings are held on the Microsoft Main campus, usually in building 118. Usually the meeting format is a presentation by a subject matter expert on a VSTS feature area followed by Q+A.
Tomorrow's meeting is in building 41. Juan Perez from Personify Design is going to talk about TFS integration with Outlook and Word. The session abstract is posted on the user group site, which is http://seattleteamsystem.org/default.aspx.
