Hi Ralph!

I found a setting labelled "email_notification,"...

In v1.7, 'Admin area' > 'Forum settings' > 'Advanced settings'

... might it do the trick to set this to zero,...

Exactly!

... or have I misinterpreted the meaning of this setting?

No, but why didn't you simply try it by yourself?

I generally do, but in my forum I have no users, only 17 moderators, and they all rely on email notification. So I seldom have the opportunity to test - unless I can turn off email notification, which I now can!

Thanks again,
Ralph
