Pinky Gone Driving Little tidbits not meant for human consumption

I'm working on a new website for the Waverly Area Celiac Support Group: www.waverlyareaceliacs.org and it's still in the very early stages. It's currently just a bunch of hand-typed HTML with some id attributes to enable using CSS. But, people keep telling me more and more things that they would like to see up on that website so I'm afraid to put too much more work into the static HTML version for fear of having to replace it with something more advance, or suffer when making frequent updates. The other option is to start right now with a Drupal-based site and never have to update, although the initial setup will take longer.
