That's not a question, but you make the cut for sheer enthusiasm. I just want to take this moment to clear up a common misconception among people who may not have used Kickstarter before, because it differs from many common pre-order systems.
The main thing I want to clarify is that Kickstarter won't take your money straight away when you pledge.
Money will only be taken from your card if the campaign reaches its funding target; and will take it on the day the campaign ends (May 31). For absolute clarity: you won't need that money in your account now - you need it there on May 31. So if there's a particular reward you've got your eye on, it's safer to claim it immediately, or risk missing out entirely.
