I was wondering what the Deny Receipt for PMs did. I have seen the little link next to PMs on my sites and don't know what it does.
It will not allow the person who sent you the PM to know you did read the PM
How would they no that anyway?
Because there's an option to track when the PM gets read.
Compose a PM look and look at the options.
It doesn't let the person who sent the PM track it, it will always remain unread.
