We can't all know everything. While this may have seemed like a simple problem to you now, at one time in your life, you also searched for this very same answer. I just hope that at that time in your life, some under-achieving individual didn't lash out in bitterness over some personal inadequacies, and make a feeble attempt at “cutting” you down.
I haven’t taken your remarks too personally, as the basic truth of your comment is already widely known. You should not take the devaluation of certification personally either; it is the way of all things. College degrees, marital contracts . . . with time everything follows that pattern.
You should especially not lash out at those that have received certification, having given any thought to the situation, you would realize that they are not more responsible for the devaluation that yourself. Such comments of yours add nothing to the situation or our, otherwise, very useful bulletin board.
P.S. Your next response to one of my questions was more useful. Giving you the benefit of doubt, thank you.
