Thank you for all of this information! I have had a difficult time with websites copying articles that I write and then placing them on their websites without any credit or reference to the author. It really chaps me with the sites that have stolen my articles end up ranking better than the original article. I tried contacting the owner of the last website, but haven't received a reply, so I have started taking the steps that you suggested in this thread.
Thanks again! You guys always seem to have the perfect answers to my questions!
