Rick,
New users when they register by default:
USER_ACCEPT_ADMIN_EMAILS='Off'
USER_NOTIFY_ON_PM='no'
USER_EMAIL_WATCHLISTS='0'
Just unless they actually set them to on, they are off. Only accept PMs are set to on.
Basically they should be on by default unless turned off. Not everyone registering checks the settings carefully, just put in the minimum required info and go.
I found that all new members complained they were not getting notifications on PMs and Topics and this was the cause.
I now have cron changing this in mysql, but a better approach is these are set on by default.
Its annoying when users get no PM email notifications or notifications of subscribed topics. It should be on by default and they turn it off manually.
