I'm looking to setup an extended family website. Something like a Facebook-ish (but simpler) site that I control on a shared host. My siblings and their kids could share updates, pages, photos, etc. in a password protected site. Some of them are "not so good" with computers, still, and even more are not comfortable with posting such things to a Facebook group or Google solutions and so on. And I'm not fan of Facebook so I'm willing to create something for our use.

A better analogy would be Yammer for a family.

What CMS would work well for such a thing? Is there something based on Drupal or another framework that can do this?
