The information in these blogs is not meant in any way shape or form to plagiarize, for I have never said this is all MY work. It is a compilation of reputable informative websites, my 'go to' books I have always depended upon & my own knowledge. I gather & put together information to help people learn & this way they can come back here to help remind themselves of said information instead of 'where oh where did I find that on the world wide web'. Seems to me it's just better & easier.
