Compare the process of forming a Meetup group. There are basic standards of behavior and usage -- applied via review after the fact, soft-security style -- and measures of activity. But as soon as you finish filling out a form describing your group, it has been created + is visible online + has its events included in a global calendar, and starts to get updates and support. Wiki Borregos has been operating in this manner for some time. See http://meta.wikimedia.org/wiki/Wiki_Borregos_CCM_Student_User_Group We originally put our info as a student club, but when it became obvious that the program to support such an organization had died, we put in to be a user group.
