Freemasons

The Grand Lodge of Masons in Massachusetts is looking at ways to engage current and prospective members with social media: http://www.massfreemasonry.org/index.tpl?&ng_view=56&ng_id=217

It will be interesting to see what develops, and whether open source CMSes might come into play.

I met a few of you at Drupalcon DC, so I know there are some of us out there. Post a link to your site here, and maybe a few implementation details (Which version of Drupal, themes, modules, etc.)

I'll go first:
North Quabbin Lodge, A.F. & A.M. - Drupal 5. Nothing fancy yet; the theme is based on Barlow and the site is pretty straightforward, using CCK/views/Date/Calendar.
