What is the 'Track Messages' section for?
 

And how do you use it? I've seen it on another forum and it allows me to see exactly what time someone has opened and read me messages and it also displays when my message was sent and what time. But when I click on the 'track messages' option in my private messaging, it says I am currently not tracking any messages.

:conf:

EDIT: I'm only asking because it could be useful for people who host games and their task involves time limits etc.

if you select Request a read receipt for this message at bottom of new message means that the person receiving the message has to confirm that they have received PM - mods generally use it
