Alright, so from what you all are saying, I just cant post these materials unless I reword them or contact the author and get permission which I cant do and i cant quote them too since i dont remember them anymore. But atleast I wont get sued right, just asked to put it down.

I dont go to school actually, my study notes comes from self study.

The school example is interesting, and I guess it is true sometimes, professors just want to recycle their assignments sometimes. But just what Villageidiot said too it is interesting how that law would apply to that.

Alright, from the way it all sounds its best to just keep it behind a door, atleast until I try to reword all of it.

Thank you all for the info and insight.
