I've been using drupal for about four days for both the Dalnet #Linux page http://dalnet.merconline.com and my home page at http://jblack.linuguxguru.net. In those four days I've managed to setup not one, but two preofessional looking websites by using drupal. This is definitely great stuff to have! I'm running the absolute latest drupal from their bzr mirror. There's been a couple minor bumps in the road.
Take a look at our web "Murcia en familia, guías de ciudades con niños". It's a guide similar to "Go city Kids", with information about leisure time for families with children. We are drupalers only for two months, but it's a great content engine. The major problems are with events and location, but we are sure we finally set up them.
