ok, maybe a dumb question. If I've enabled Pushover for XenForo.com, there doesn't appear to be a way to disabled it. There is the "Associate with Pushover" button, but no "Disassociate".
And the User Identifier, XenForo username and password are required fields once they are set.
EDIT: Never mind, just saw this "To disassociate and disable receiving XenForo alerts via Pushover, remove all user details."
