We've launched the SoCal Team System Community site (http://www.SoCalTeamSystem.com/).  Our goal is to provide a more centralized area for Team System-related information that's specific to Southern California.

In the interest of time, the initial site leverages Office Live Beta (http://officelive.microsoft.com/).  We are planning to create a custom site to eventually replace it (with much more content, discussion forums, etc); but for now, you can still find general Team System information, SoCal events, and information about MS office locations.
