Actually, I'm kind of wondering the same thing 0.oI guess it's in the profile somewhere.
I had the same problem, but there´s a way to solve this.Say, that you want a private message, this will show you, what you got your karma for (and on which post)
The permission thing is still bad. Hope it gets fixed.Only said that the PM thing works. You get a message from the oracle like this:"Dear user. Your karma was changed.The reason of changing was: <reason for change>Your karma was changed on this message <link to message>"
I'm wondering the same thing too. Good thing to know that if you change the settings to PM now you'll receive a PM for future karma.
