Rick,

I seen this and just have mysql upodating profiles, but 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. Accept PMs are set to on.

Basically they should be on my 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.

Thanks!
