Everything here looks great, getting excited about this already. I love the graphics, the theme, and the hashtag will make it a lot easier to find others to re-tweet. My only suggestions from promoting In It To Win It are to make sure that everyone clearly knows that the site isn't accepting any money itself. I came across that a lot, people asking if it was "official" or having people post a warning to others that it was a scam. It felt like I was wasting so much time having to post on every "scam" comment because once people see that word they're unlikely to click on it.
Also, I'm not sure if you only want people to sign up if they are actually going to donate themselves but I saw a lot of "I wish I could help but I don't have any money" or they wouldn't join the event because they weren't sure if they'd have the money. I'd tell them that they could still help by joining the event, inviting their friends, and changing their profile picture. I figured that would both help spread the word and remind them in case they end up getting money later. So maybe have the part where people enter their email say something like "Sign the pledge to Rise For Liberty - and be reminded about the moneybomb".
