The idea of rust is stupid, 1: If the lock is indoors how would that lock be able to know? Rust doesnt just occur after a week while indoors. Even outdoors, it takes years to get to the point where it just falls off.
Although I have to say, if we required Spoutcraft it wouldnt be so bad, MOST people can get spoutcraft and the possibilities with it are great. I just got it to work and am loving it. I can switch between 1.8.2 and 1.0.0 for kiwike
