I am really curious to hear peoples opinion on this. My stance is that yes it is ok and Ill give an example. Anyone who has done any Ghostbuster propping has heard the term "Stefan's plans". Most people agree that they are the best plans for building a proton pack, and almost everyone who sells pack shells uses his plans for their build. He put in hours and hours of work to make the best possible refrences for all of us to use, and then put it up on the internet for free. Now just because you have access to these plans does not mean that you are capable of making great bucks or molds. It takes tons of skill and time to translate stefan's plans into the real world and no two "stefan accurate" packs are the same. I see pep files the same way. They are a great start and the people who made them are heroes of our community, but it still takes time and skill, sweat and tears of the builder to make them and finish out the details, and if they want to make and sell copies of their work(as long as they acknowldge the person(s) who made the pep file) that is their right. How do the rest of you feel?
