You will find Private Messages (PM) showing up at the top right side of the page next to your username (it will have a number next to it with the number of pm's you have). (see below image)
when you click on your name a colum will show up ... see second image - if you click on the envelope you will be directed to your incoming PM's.
Hope this helps.
