Does anyone know of any open source social networking software? (something like facebook.com)?

I'm part of an organization that has had many members over the years and I'm looking for a way to set up a website that will allow all members to create profiles, upload photos, etc. and immediately link up with one another. Something similar to social networking websites but this one allows everyone to automatically connect with one another since it will be limited to members of the organization.

Does anyone know of any open source social networking software? (something like facebook.com)?
What about one of these?

Reply:I'm not aware of anything that is created for redistribution. The size and complexity of such a site would suggest that finding a canned package to do this is unlikely. We're talking a lot of resources to run a package like that in it's purest form. If you wanted to build a framework and offer up cookie cutter pages, you could do that rather easily with Apache, MySQL and PHP pages.
