I'm playing around with the Drupal configuration that Chris set up and am slowly getting the hang of it. You should be able to register for an account. It requires approval from an admin, but it should come quickly. Its mostly to prevent spam registrations. Once you have an account, you can post blog entries and create content.
Blog entries will end up showing on the front page and can be categorized by user. I've also enabled the event calendar on the right hand side and you can add events if you're a registered user.
There may be a need for a tutorial to be written or a short training given to people unfamiliar with Drupal. But once you get the feel for a content management system (Drupal or Joomla), you'll never go back to making static web pages again...
