Susie...I sent Razarooski a PM.... He sent me a PM in return...usually, when you read a response, your original PM shows up underneath..instead of my PM being underneath.. a PM that you had sent to Raz showed up.
Oh, I didn't realize it was YOU I was responding to <ducking and running>...
False alarm. There was a minor bug in the system that users could use to show someone else a PM written to them almost as if it'd been written to the "someone else" rather than the original recipient.
That bug has been squashed.
Only the original recipient of the PM could make use of that bug. So there was no random reading of PM's happening.
