Anitha - It's perfectly ok for you to call Charlie yourself. He's very personable and willing to speak with any shareholder. He doesn't ask nor care about how many shares you own.
He can't and won't speak out of class, however (I've tried!). I spoke with him a couple of times shortly after the last 8k. I don't report what he's said to me, even though it's not inside info, out of respect for the privacy of our conversations. But you certainly can call him. It may help you feel a little more comfortable.
Regards ...
