Thanks for the review of bbpnns :). I’d be great if you could review it in wordpress.org.
Now that I understand your needs, just go ahead and de-select the Subscriber checkbox role from Settings > Forums > Email Notifications, but make sure Override Subscriptions… is checked.
That way you will not have mass mailouts to SUbscriber role members, but will still have the benefit of controlling the body of subscription mailouts.
Cheers!
