For the most part you we are out of luck, I also recently moved. The post office is the only place to put in for a change of address, FedEx and UPS don't offer that service. We left our number with the person that bought our house and asked them to call if any mail gets delivered for us but who knows if they will. You can also change your mail address for company that you have a profile, so if you happen to win from them they have the right address. Kind of a bummer but you cant really dwell on it.
