I too am totally puzzled why some people have objections to this site. David Mellor is a highly respected Music Technology expert. He has written courses and exams, given lectures and is a regular writer in leading magazines. The site is informative and useful for anyone learning or using Music Technology. I have never received any spam from him, nor anything which could be misconstrued as being aggressive or unethical advertising.

This site by David Mellor does not go out and snag people. It caters to those specifically interested in developing audio mixing skills. The weekly newsletter often has articles of interest to those interested in audio. I have never taken one of David's courses but I have purchased several of his text explanations of compressors as well as other similar topics with no regrets. I am not sure why others would downrate this site. Possibly it is because there are recurring offers for enrollment in his classes. But this site offers interesting and helpful information for free. I have never received an malware or adware via this site. Never had a bad retail experience either.
