Visitors to http://Greatnonprofits.org can find, review and discuss nonprofit organizations with ease. The website features user-generated content so visitors can learn about the pros and cons of various organizations from the people who have experienced them firsthand. Posters to the site include volunteers and donors to nonprofits, and people who have received services. Users can also write reviews of organizations on GreatNonprofits’ partner site, GuideStar. Organizations that get the most positive reviews in August and September will be featured on both sites.
