As someone who is involed in what may be called the creative industry, I design and develop Training and Development materials, I am more than aware of the cost of plagiarism. I spend a huge amount of time and resources on the development of courses and worksheet/books, only to find that within a short amount of time someone has copied it and is selling/using it as their own. I am sure the same feelings are shared by software developers and musicians who suffer at the hands of priates. I don't copyright my work because I don't believe you should beable to own ideas or knowledge, the only thing I ask for when people use my work is for them to reference my contribution. Is this too much to ask.
