The Erasmus Student Network (ESN) is a volunteer organization with 250 local branches in 33 European countries. Every branch had its own, often bad and unmaintained, website and a deep reorganization was needed. We will describe how we achieved this, and much more, by using Drupal.
We chose Drupal for a common website template since it was easy to customize (we added a ESN theme and preconfigured some modules), to administer (volunteers are not skilled webmasters) and extend (so that every branch would be able to activate the modules they needed). We then moved on to building a full distribution profile: we will describe advantages and difficulties of this move, which eventually led to our aim of making our website template easy for anyone to install and administer.
A great benefit we got from choosing Drupal was the possibility to visually aggregate data into one website, called the ESN Galaxy: thanks to Drupal's built-in RSS feeds, we can now automatically track the activity of local branches, gather it from the individual websites and display it on a summary page with maps.
