:D lol, that's one way to make it work.
Yeah, I broke the PM system a while ago, and since practically no one was using it. haven't gotten around to fixing it. I just finished a rework of the visual layout of the notification system, which now makes it actually possible to notice if you have new messages, and fixing the messages themselves shouldn't be too hard.
I can't see the content of any private messages. A person I talked to reports the same. So it must be true for everyone, based on the well known principle that that n=0: plausible hypothesis, n=1: near certainty for personal purposes, n=2: established science.
Btw, it's currently possible to set up a private two-way communications link by repeatedly editing the title of a conversation :)
