Two things -
1) Do you think maybe it is a Safety & Soundness issue? Our SS examiners (FDIC) always ask for our org. chart, but it is not required to be posted to employees. They ask for the chain of command to determine that certain functions are independent of others.
2) Being able to email your regulator is truely a convenient access method. However, I would caution you as to how often you use this feature. I just had an exam and the lead examiner was discussing with me that he had a bank where the Compliance Officer emailed him constantly for advice. At first, he was not too concerned. But because the emails kept coming, he now has very little confidence in this person. He even went so far as to ask his supervisor to discuss the matter with the bank President to end the emails. I'm sure you are not doing this - but I thought the other readers might want to know that while it is nice to discuss some matters with your regulator, too much reliance on them minimizes their confidence in you.
