tutorial is fine.
tutorial is almost explained correctly,ALMOST. but i recommend learning how to script better yourself before instructing others. i relize your trying to help but honestly,a code that basic should be written better,and i know what im talking about. it just wasnt explained right and the code was sketchy. but i reccomend you look at some tutorials yourself. i dont want to sound like a dick but remember this is my opinion and i dont doubt this will help others and im reviewing this in their perspective as ive been using as for around 3-4 years now. i voted 5/5 for the protection point but i think its more like 3/5 and 6/10 because you put an effort into explaining it instead of throwing code out there :]
