How do I add my pheromone stash list to my signature?

Hey everyone
I have a really simple question to you all.
I have noticed on other peoples messages - right at the bottom is a list of each persons stock pile of pheromones. Can anyone be good enough to tell me how this is automatically added when you message somebody?
Cheers in advance.

go to your cp and add your list to your sig

Thanks Radman
Question is now solved.
