It is true that the makers of each mod/skin/map should be given full credit for their work, but by telling him to shut down the mod and such...thats a bit harsh no?
Since it seems that his first language is not english, maybe some of US who do speak fluent english can help him contact each author and ask their permission.
Of course, Tim would have to add a credits page to his mod, and in the readme, including all of the people that worked hard to make all those things.
But congratulations to you, TimFX, for working so hard on this mod. I truly hope that we can help you get the author's permission and that your mod will find great success!
Lets make this happen, instead of shooting it down before it even gets a chance!
