Dave - YourEmail was rec'd on the mailing list. I thought something was messed up w/ my account on the mailing list, but what seems to happen to me is that I don't receive my own replies to a post on the email list. So, then I don't think the email is rec'd and posted. But, I did a test a while back and Andy graciously replied as well w/ a few others...
