It *is* kind of a one-liner.

Adding events management to Drupal 6

  1. download and install the event module
  2. download and install the signup module
  3. enable the event module and all its sub-modules (don't check datepicker if you want to go fast, as it will require additional CSS and JS to work)
  4. enable the signup module (requi
