Hi jlove973,
You will get a notification if you've had a response to your PM. It will be a flashing envelope (up at the top of the screen, can't miss it!)
Taken from the FAQs:
</font><blockquote><div id="quote"><font class="small">Quote:</font>
What does the flashing envelope icon on the Menu bar denote?
It means that you have unread Private Messages.
What do the letters in the Received Private Messages display denote?
'N' denotes an unread message.
'R' denotes a message that's been replied to.
A space denotes a message that's been read but not replied to.
</div></font></blockquote><font class="post">
