Imperial College Fairtrade Society
Back in the days when Fairtrade was still a young movement and not a silly trademark owned by a dysfunctional multinational group of organizations, I was the president of my university's Fairtrade Society.
As with most student societies, my impact was short-lived. Even that Drupal powered website I made and was very proud of was promptly shortly after I graduated. I'll let some poster designs and scanned newspaper articles which I found on my harddrive tell the story (scroll left →).
