I've just seen this and I do want to donate but first I want to know what happens if the full amount isn't reached by this deadline?
You could see if Cort will put something on his site about this to help with donations if it hasn't already been mentioned there http://www.cortjohnson.org/
They've already started the work because they're so confident that they'll achieve the amount eventually, so if you want to donate, I wouldn't hesitate. It seems a very achievable goal to me.
