XF 2.1 Email Preferences - Is there a global default setting


Active member
Many of my new members complain that they get lots of email notifications regarding user post etc.
Many people do not like to be bombarded with emails every day.
There seems to be so many email settings under their account in Preferences it is a bit mind blowing for a newbie.
Is there a way that I can set email preferences to no (except from admin) as the default for all new members?
