Answer:
You have two options for running a Cultura exchange:
1.The Cultura Drupal distribution provides a setup for exchanges and the ensuing discussion. See the Educator's Guide section on the Cultura Drupal distribution for more information on installation and use. You will need IT support at your school to install and run the program on your school server.
2. A Cultura Exchange can also be run by using Google forms to create questionnaires and collect students answers, and a WordPress blog to publish the answers and enable students discussions.
