This project began from a need to integrate a Mambo 'library' and a hand-crafted html site.
The migration was simplified through the use of modules including Views Bulk Operations to help with reclassifying the old cataloguing system in to one that made sense under the Drupal Taxonomy approach.
Further customised solutions were provided for the Summer Steps project which was part of their Walk to Work campaign. Teams of various sizes were able to record their team members walks over a period of 4-weeks, with the walk log being able to be entered as time, distance or via Google Maps.
CiviCRM has been used for their Membership system.
