This was the second cohousing site I did, after our own. It has what I think of as all of the essentials for a cohousing group website - public content about the group, plus an events calendar. It also has a members area for group members, including a contact list built in CCK.
Because the site maintainers are not html folks, this site is set up with the TinyMCE editor, a WYSIWYG content editing module for Drupal. (You don't need to know a lot of html to maintain drupal content, but it's nice to be able to center and bold things and the like.)
This site is built on the foliage theme.
