I get asked quite often for a holistic list of user groups in Southern California so I have compiled the list of Microsoft Developer focused user groups that I know if. Do not came this is the holistic but I hope that others will comment about other groups.
I hope all of the groups on this list are registered on codezone.com so that can be more of a central place to get a holistic list. By the way the nice thing about codezone.com is that there are some (but there needs to be more) non-MS focused groups listed there as well and I think it is important for all developers are going on in there overall community.
