I host, develop and maintain (among others) some websites for non-profits, and I'd be interested in moving them to a CMS to make it easier for others to help maintain them. The sites I'm looking to move now are:
http://www.theseriousroadtrip.org/
http://www.sexworkersproject.org/
Each site contains a certain amount of 'fixed' content, plus some pages based on one or more pieces of fairly 'structured' data. For instance, 'theseriousroadtrip.org' has sets of pages that relate to certain 'things' - member organizations, projects and so forth - so much of the content consists of an index page that lists the 'things' of a certain type, and then pages that show all the information about an individual 'thing'. The 'sexworkersproject.com' has primarily lists of things - links to resources, downloadable reports, etc. Currently, these are implemented using PHP/MySQL.
My goal would be to make it easier for a small number of contributors to add content to certain areas of the site. I don't really need blogging or forums (one of the sites has a private forum, but we already have a tool for that). I'm just looking for a way that users with little or no technical skill can easily add or update some material that follows a well-defined structure. I don't want to have to bend over backwards to fit my model to Drupal, or Drupal to my model, and I want to preserve the existing design insofar as possible.
