Voting is now open for World Challenge 2011. It closes at midnight on 11 November. Please spend time on the site reviewing all of the 12 Finalists (don’t forget to watch the short videos) and then vote for your favourite (one vote per person). The Top 3 Finalists with the most number of votes when voting closes will take part in our Final in Amsterdam in late November. You can view the Voting Terms and Conditions here.
