What is Copyup? Copyup means that you can use for your own purposes what you find on this website. In doing so, however, you must keep that material free for other people to use and you must give credit to I encourage the use of these materials with the idea that you are learning from it. So, pass it on and teach another. Sometimes imitation is an important part of the learning process.
