If your goal is to create reliable connections between QuickBooks users and those offering services and expertise, why won't you accept my CPA license as proof of identity.  If the State of Michigan believes that I am qualified to render these services, what's the problem? 

And since when does my driver's license proof that I am qualified to advise others in the use of QuickBooks (I also thought it meant that I was qualified to drive a car)? Isn't that the purpose of your tests?
