I messaged SR about the new PM system when I got the notice of changes from him, and it contained previous PM's.He said that it will show previous PM's that have not been deleted by BOTH parties, or that are stale - over 60 days old.I agree that as a vendor it's nice to have a history of PM's there, allowing me to keep a clean inbox counting on new PMs to have a history, if the person sending has kept previous correspondence.You should always assume that any information you put out there is out there permanently, so as long as you always PGP critical info like your address.Like any new feature, it will take a few days to assess and work the kinks out, and SR has lately been swift to respond to any issues, once the new features have had a chance to be examined in depth.
