The Law requires that you put something of your own substantial spin on the material. Generally, if it smells like a skunk, it is a skunk. It is considered GOOD FORM to cite your source, EVEN IF you are making someone else' idea your own. For example, if you want to write your own article about copyrights based on this one, you should ask for permission to quote me or at least cite me as the source for some of your material. If it is found on the web and you're publishing on the web through rotation.org, provide a courtesy link.
Copyrights exist the moment the copy is created.
