Well I may not be able to use these for any comercial venture, but I am still learning the program and these will be great for that. Thanks! :)

As for all the legal side, this is starting to sound like the situation in the music industry where people would use samples from other songs in their songs. I think that is still being gone over in the courts isn't it? Kind of a situations where laws have not caught up to the technology. :) All the legal stuff is too messy for me, so I will just be playing it safe and using free ones I find for my practice and will buy/make ones when I am ready to do comercial work. :)
