its kind of like a email system
its called private messaging
people can send messages to each other in which only those two can see
In the upper right hand corner your window should say
Welcome panthers4ever
then under that private messages in which you can click on it
youll get the hang of it within a week or two

i think you do it in your settings. try clicking on the link in the top left that says "user cp" and i believe you can change it there. as for PM, it's just a message system to communicate privately between you and another member. kinda like a simple version of email

for pm's you just click on the persons name where they posted or replied and then it will give the option oif PM'ing along with several others. img...dunno that one, sorry.
