Some Drupal sites I've done
A publicity and information site for Loop Abroad, a summer study abroad program for high school students. The owners are able to easily add complex pages and have the site's structure and navigation adapt automatically.
A donation system for United Way of Massachusetts Bay and Merrimack Valley. It is configurable to support multiple fundraising campaigns, event registration, and simple workplace campaigns. Extracts and reports are provided for UW admins.
This is the org site for United Way of Massachusetts Bay and Merrimack Valley. Lots of fun with organic groups and domain access to create targeted community sub-sites.
This site is for members of a United Way affinity program. It has about 50,000 members from several United Ways. It uses organic groups to allow each United Way to list their own local offers along side a national pool and send their constituents targeted messages.
The site of comedian/actor Dave Russo. He manages all the content, and his posts are sent to his mailing list.
inspire4life.org started as a support site for a youth summit in Boston, but it is growing to be a site that collects all of United Way of Massachusetts Bay and Merrimack Valley's work on youth.
