Hi spymare, its not quite like PM its just really saving a copy of any messages that have been emailed to the seller so they can save, delete or reply. Its not for everyone, but as i said it was the most requested feature in a poll i had on my site and if anyone had been offering it i would have bought it instead of having to do it myself! Tried a couple of wordpress PM plugins but most were really bad and didn't really work well with CP so i built my own.
