hey alex,
no there was absolutely no probem with the email. I was just thinking about that because at the same day I got some mails talking about that permission.
but don't mind, in the meantime I changed back to use email because this is also needed for notifications and so on...
so the problem has gone ^^
I also had a first look at 3.4 - really looking great and the k2 integration seems to be really nice - great work
