This is the entire point of the Stake your Bitcoin Address thread here:
https://bitcointalk.org/index.php?topic=996318.0 except instead of PMing the bitcoin address to a newbie, your address and a signed message is posted publicly, quoted for records, and verified by multiple trusted members of the community.
Thanks for the link.
There's no harm in using the belt and braces approach though. Anyone who wants to pm me their address is welcome to. I'll still have a copy if someone hacks your account and deletes all your pms.
You won't if someone hacks your account and deletes your PMs. Who knows if you'll even stick around long enough to be of service for this. You can pm default trust account with your address which Theymos has access to or just post in the thread already suggested so this is all kind of pointless.
