We are the organizers for the "Cooking Cup", Germany's national hobby chef cooking contest by SIEMENS home appliances and ELLE bistro magazine. For our website - which changes looks and content each year to reflect the year's topic of the contest, we've been using Mambo for years. However, we truely outcrew Mambo and have successfully been moving to Drupal! For the beginning (as of my writing Dec. 2005), there isn't much interactive features on the site yet, but this is to come in early 2006 when we're gonna have a community recipe area on German Cuisine, comments enabled for users, personal blogs for contestants and anyone interested, article writing for users, and many more things to come.
