I took a class by Tom Givens, he gave us a lot of that same advice.
While passing on info from other credible instructors is great it looks like you are trying to give yourself credibility by using their words. And failing big time. This is probably the forth similar post I've read where input from several well known instructors was put together and presented with the "Compiled by" or "from so and so" disclaimer.
Better advice would be to advise someone to just buy Fighting Smarter if you have no original content or new ideas to add. I actually think that's still considered plagarism as there was nothing of value added to the massive quote, even if it's not it's called **** riding where I'm from.
