Hmm Good idea but probly doesnt work

I just had a random idea for my TD Map as we all know people like to edit TD Maps *cough WinterMaul* anyway

I was thinking what about a way to make it so people can edit:

The Units
And
The name of the map
but have it so theres no way to change the terrain/Copyright/other stuff like map size Most triggers

Just an idea dont flame or anything and i know it probly doesnt work or is Very hard to do

I think that it, indeed, is impossible to use map-data to limit WorldEditor's usability.
