This is for a letter that I am writing to someone who is now a friend and who I have tutoyered for a few years, however the letter will be a formal one adressed to her in her position of the president of our diving club, I was going to start it "Madame la Presidente", so I guess that is the first question is, is this the correct formal way to address her in writing?
Its a fairly serious letter, a bit of a shot across the bows requesting her to follow an administrative procedure laid down by our governing federation to accept and validate my existing diving qualifications, something "the club" although not her personally, has steadfastly refused to do for a couple of years before now. I say her, in fact it is the club that I want to abide by their responsibilities but there is a chance that she may just personally and discreetly send off thye dossier to avoid the fireworks that it will cause.
My gut feeling is that I should use the vous form, perhaps qualifying it meaning you the club officials, maybe "je vous demande (vous les responsables) .......... " etc.
Does anyone know of the correct way of doing this?
The problem is definitely not her, or indeed any of the members of the committee other than one particular individual who rules by force and intimidation.
