I’ve had a chance to really use WordFlood now. Have to say, I like it. It keeps track of your changes and let’s you know how much of the PLR item you have turned into your own stuff. It did not take me long to change one article (experimenting) by about 45%. That’s pretty cool. You can also add words to it if you don’t find exactly what you’re looking for while editing. Again, cool. Check it out here - Wordflood
