also you can get yourself banned for this

How can you get banned?

ISn't it just your own files? so ur not hacking the site or anything. Plus they change back once you log on.

I prefer to use the texture previewer, myself, to preview my sets.

He probably didnt know that this had already been done, but stealing tutorials is pointless and stupid. So, if he did intentionally do it then let this be a lesson to him to not do it again, otherwise, just check that a similar tutorial doesnt already exsist before you make one.
