The Team Foundation Server bits which you can download from MSDN (find it here) represent the full product - complete functionality and connectivity.  The only difference is that there is a evaluation time limit of 180-days.  Once you obtain your product key, you can simply enter your product key and remove the time limit.

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.

Enjoy!
