I've had a lot of trouble with emails and people setting passwords so have decided to turn the "Enable User Registration email confirmation" OFF. So now I can get people to register with relative ease, however they are not getting any email for registering. So do I need to turn "Overwrite WordPress New User Registration Email for Users:" to "NO"?
If you've disabled this option then why you wait for any email? The email is only for setting the password. So if there is no password setting step then there is no email.
