I got word from my colleague in New York, Sajee Mathew, that a NYC VSTS Users Group has recently formed. They are going to meet on the 4th Tuesday of each month starting at 6:30 PM at the Microsoft Offices in Manhattan (1290 Avenue of Americas, 6th Floor).
The first meeting will be on September 30 and the speaker will be Claude Remillard, President of InCycle Software, who will provide a VSTS overview and roadmap.
You must register for this event. Food and refreshments will be served.
Note: The group's site requires that you have Silverlight 2 installed, so if you want to attend but don't have Silverlight installed yet, you can visit the Microsoft Events page and to register.
Hope to see you there!
