Elgg is an open source social networking application that was created for schools but can be used for any group. At this point only users that are approved by the admin (me) will be activated. So go ahead and register and if I recognize you as part of our immediate-ish family I will activate your account.

I have set up some initial functionality like file manager, where you can upload photos and a blog, where you can contribute content to the site.

Let me know if there is other functionality you would like.
