Be careful!
You might want to be careful about 'bugging' the chief pilot office. An assistant regional chief pilot told us stories about some guys that had 'drowned in the pool' after being hired by calling the chief pilot office ladies and acting like an a$$. And these were guys that had been hired! IMHO, just send updates (quarterly) by priority/express mail with delivery confirmation. You'll know they got it, so you can relax. Just my 2 cents.
