How it works.
1) participating non-profit organizations register for free at noprofeed.org – they only need a site able to send an RSS feed with their news;
2) bloggers and site owners – based on WordPress – looking to help non-profit organizations, install the freely available noprofeed.org plugin; then they can easily configure how the widget used to display the feeds should look like on their blog, including colors and size. Finally the blogger sets a number of parameters about what kind of contents will be presented by the widget, including the country where the non-profit organization operates, the language of the feed, one or more tags (such as: education, environment, etc.). From that moment on the plugin will take care to download the relevant data once a day and to feed it to the widget.
What a better way to help non-profit organizations?
