The issue isn't "We didn't save up for the event". My mind is blown that people keep jumping to that conclusion. What happened here is a case of allocated money from a sponsorship source where the release of the money MAY BE DELAYED past Evo, effectively rendering it useless for getting us there. So the money allocated for Evo exists, and is 100% coming, but the time is an issue.
So this donation drive is less about giving us money, and more about helping us get to EVO, then you getting your money back if you choose to.
