Forgetting for the moment that he very likely has no internet access... really??? Nearly half of his town has been wiped out, he almost certainly knows people that have been killed, and he may have to struggle to get food and clean water. And you assume he should have come right on the board and posted? Get serious.
Look, we all want to hear from him, but we need to give him some time. The good news is that he isn't listed on any lists of fatalities or missing people, if the info we have on him is correct. So let's hope for the best, and respect that he's got more immediate concerns than posting on American.
