Visual Studio Team System User Groups
Some one asked me yesterday for a list of Team System user groups. And Chuck pointed me to his blog post here. This is probably not an exhaustive list. If you know of other Team System user groups that is not on this list, leave a comment here or in Chuck's blog.
From Chuck's blog:
Domestic VSTS Usergroups
Chicago Visual Studio Team System Users Group
International VSTS Usergroups
