I have loved advent calendars since I was a kid. I never stopped buying one for myself and recently I have had miniature calendars, some got from swaps, some bought (Lundby has made cool calendars). Three years ago I introduced a picture calendar in Nukkekotiwiki and it was really popular among the miniaturists. We have had it for 3 years now and now that we have the new wiki I am bringing the concept there too.
The idea is that people reserve themselves windows and then they fill the page with something related to Christmas miniatures.
