It's staggering what one person can accomplish these days with the help of the internet. Take Christine, a UK student at Leeds University. She was shocked when she heard that Syrian students at her school might be expelled and even deported back to the nightmare in Syria because they couldn't pay their school fees, some because their families had been killed or impoverished. Christine stepped in and actually saved hundreds of students at dozens of universities from this fate!

She did it by getting together with some friends and starting a petition on the Avaaz community petitions website. The petition was good, sensible, and emotionally compelling. She only sent it to a few friends, but they sent it to more, and it soon blew up on twitter, with over 45,000 people signing! The Avaaz team helped Christine get the story on TV and in major newspapers, and government ministers pushed schools to waive fees and launched a plan to make sure no student ever faces expulsion because of war back home again.
