Nassella.com is a free community bulletin board and news aggregate site for information of interest to people working in California's environmental and sustainable development fields. This was my first project with Drupal which took several months to develop after much frustration and a lot of help from the Drupal community.
I've tried to develop the site with the user experience taking the highest priority. Key features include faceted search for easy filtering, date/calendar modules, Feed API and the use of the location module to geo reference nodes and content types, which include green jobs, events and courses located in California.
Several other modules were utilized - primarily to achieve an intuitive user experience, which based on my experience takes a bit of work with Drupal. If anyone has any questions please let me know.
Cheers,
Ian
