Okay, when we click that link it takes us to a registration page. Could you please tell us about your group and what you are?
When you say backed by Muse Games, what does that mean? Does it mean you emailed Bubbles and he said it sounds like fun, or does that mean you're going on the website? Could a Dev help out here?
Child's Play is an amazing charity. We're a great community, and we've been successful in the past for raising money for a kickstarter, but not for a charity yet. It sounds like a terrific idea, and it's great of you to get the ball rolling. Having said that, I don't think any of the teams would rather take half the prize money for themselves rather than dedicate it all to Child's Play - so you might want to look at that part of your pitch again.
Would you please tell us about you and your group? I will admit it makes me nervous that you only have 26 members.
