Dick Greenhaus: The USPS web site say they ARE available. See the link in my last message. What grounds do you have for saying they aren't? I'd be very surprised if the USPS failed to keep its website up to date.

For example, see this page: National Mail Service Updates whose purpose is to announce temporary interruptions of service. It says prominently "This information is updated daily," and the page bears the date July 22, 2011. Note that it lists M-Bags as one of the services that are temporarily suspended to Libya. That implies, doesn't it, that M-Bags are available everywhere else?
