I put this in the same category as "Certified Wedding Planner". I highly doubt that any of the goobs who paid big bucks to become certified can honestly say that the cert paid for itself. In our world, you'd be every bit as effective to just make up some "We are Greenie-Weenie Approved" crap and put it on your own materials. Yea, there are airheads who actually might cozy up to the notion but those same airheads will never, ever question your so-called credentials. If the milk is free, why pay for the cow?
