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.
