Protecting a map

I'm currently working on a new Open RPG. I've got alot of it done, and before i realease the beta for testing, i want to know how to protect a map. This map is kind of like my happy little project that i dont want anyone to touch. I'm tired of seeing rigged RPGs where one hero has been edited to be better then the rest.

Is there a special trigger you use or something?
i could really use the help.

Through the simple process of searching the forum you will have your answer in no time flat.

Just give it to some friend of yours to be tested.. Then you wont need any protection..

My friend and i will be testing, but, when you have people who didnt work on the map themeselves looking or bugs, they find them faster then you. And i tried to find the forum search, but i havent been around very long, as you can tell by the sheep. Thanks for the help. i appreciate it.
