Like I said Derek, not after any argument with your good self or anyone else. Paul Evans did make a very good point, "if the ncca has no value" why would you or anyone advertise you are trained by them and include a link to the website?
All I am saying is:
Some customers could think you are a member when they visit the site from your link, even though I do understand that it actually means nothing and they wont get a better clean, but, big but, you are not doing the ncca and the 600 ish paying members any favours at all.
BTW imo the ncca are not doing anything wrong in allowing novices to the industry in joining because as I have said before, passing an exam and having the best and most powerful equipment doesnt always mean you would do the best job possible.
