It's up to you. Where most of us have a link to our eBay auctions or a random joke, Rayman has taken the time to put a link to his where there is a website. You visit the website, click on the button and you could save a childs life, or help fight breast cancer, or save a bit of the rainforest. It's up to you. You can do them all. There's nothing to sign up to, nothing to buy. It's all sponsered by the stores who have their logos on the sites. It's really worth doing each morning when you wake up.
CHANGE THE WORLD!! DO IT NOW!!
