Hi, last year Drupal was the most popular and one of the highest rated content management systems in the Non-profit CMS report. The report last year was done by NTEN.
If you are interested in getting your business listed as a sponsor for this report by Idealware, please visit http://www.idealware.org/os_cms_report_sponsors.php.
Our article comparing Joomla, Drupal, and Plone gets more than 2000 unique page views per month, and is in the top four Google search results for any combination of the three platform names (i.e. "Joomla Drupal", or "Drupal Plone"). We will strongly promote the new report from this older article, throughout the nonprofit technology community, and to our opt-in list of almost 7000 people (of this list, 71% help nonprofits with technology decisions, 67% are with nonprofits with an annual budget of more than $500K, and 36% are with organizations with a budget of more than $2 Million).
The report will include both a consultant directory and sponsorship opportunities, and we'd love to include you.
