nope. well I know I cant, and rather sure no Mods can.... reason being when people abuse the PM system its about the evidence forwarded to us. There's never been a discussion " i saw bob's PM that he sent gary saying he was going to cut his throat in his sleep tonight" ... so to my knowledge no
I once asked why i only get notification when my box is full on my email and dont get notification here at the rx , and he told me the pm features are a v bulletin deal and the rx isnt notified.
Well just to be on the safe side every few weeks I send a PM to another poster, talking about what a great job the Mods are doing. Cuz ya never know.........
