Fuji Abound has offered some very sensible advice, but to make it work, we all need to be absolutely clear about what the issues are. It will only confuse the message, if the officials we write to get different interpretations of what's going on and what's at stake. Hence, I'd add one extra point to Fuji's list: publish somewhere a concise explanation, with references to any supporting documentation. Ideally, it should be a PDF file with copying prohibited, to discourage the sending of identical messages, which are more likely to be ignored.
