I have been looking, and cannot seem to find if this already exists. I would like to change the notification email users receive when they get a private message. I would like to hide the text of the PM, instead force the user to click a link to view it. That way, people will not reply to the email (which happens a lot), but will be forced to view the PM on the site.
I found "Don't allow post text in notifications?" under Features and Options > Basic Features. But, that seems to only hide the text a user receives when they are watching a thread.
Hoping someone can point me in the right direction.
