How much did I need to say?
I am going to resign as President of a volunteer organization that I've become more and more disillusioned with over the past three years.
I feel all I need to say is "For personal reason, I am hereby submitting my resignation as President and member of the board of..." and leave it at that. A close friend suggested I may want to say more, but quite frankly, I feel that covers it enough.
There's a lot more to this, but I don't want to go into all the gory details.
I always appreciate the input I receive here.
