You're actually right, Scruffy. It doesn't say anything explicitly about witches being able to PM each other. It does say that PM'ing is forbidden if not explicitly stated - although I think it says in the same rules that I'm not allowed to give a quote, so you'll have to check yourself - which strongly suggests that SOMEONE can PM someone else. I guess I misremembered that to think that it said that only witches could PM, because that fits with what I already knew about mafia.

Having said all that, I'd be REALLY surprised if they couldn't PM each other at night at the very least. Regardless, in every other mafa game I know of, mafia are told who else is mafia. With Karifean in charge though, who knows.

I still think it's safest to assume that they can PM each other, and proceed accordingly.
