Cool, first thing you do is make a copy of this letter. What an accomplishment to know you have shown up on the governments radar and used tax dollars to fund the investigation, the letter, and any other man-hours that might have gone into this. Lastly, laminate the letter that you copied, put it on your fridge, and put a gold star on it. Well done sir. Oh, and sign it, send it, along with a typed letter with your explanation.
