Gotta disagree. I've called the OFAH about a dozen times in the last couple years with various questions - some questions were straightforward, others were a little detailed and confusing. I have never NOT gotten a satisfactory response from someone at the OFAH, although I sometimes get bounced around between people. I can't say the same thing about the MNR. The staff at the OFAH are very knowledgeable and much easier to access than anyone at the MNR.
