Maybe I just get easily confused ... but, is there a way to automatically save all sent PM's. There's a check box to click if you want to save individual PM's as they're sent, but usually in the flurry of sending I overlook it - and then I can't remember whom I've sent what.
Unfortunately, no. At least not that we've been able to find, anyway. That's something we can bring up to the support people, but if there's not a known hack for it, I'm not sure it would be worth paying them extra money to develop.
