Last night, as I lay in bed, a thought hit me.
There are many themed Advent Calendars. They used to be aimed at children, but these days there are many aimed at adults too. As a fifty-two year old kid, I was looking forward to opening the first door of my LEGO advent calendar, while my partner had been talking about her very expensive Whiskey calendar.
So, it hit me. Drupal needs an Advent Calendar.
