Over one year ago Viva! Akcja dla Zwierzat has launched a new version of the "30-Day Veg Challenge". The program has been very successful, with thousands of people signing up for the challenge. As the whole concept is based on either free or very cheap internet tools, it has a benefit of being very efficient and making feedback easy. The presentation will cover the technical details of the program and all the fun numbers and statistics that all activists love.
