Sorry...dumb question. If I have sent someone a PM, how will I know if/when that person responds?

At the top of the page click My Account. On that page click Forum Settings. At the bottom of the Forum Settings page there are options to receive email and/or a pop up when you receive a PM. Click on the box next to the option you select. I choose to get a pop up notification when I get a PM. That way if I am visiting RCU I get the notification as soon as the PM is sent. If I am not on RCU when the PM is sent I get a pop up notification as soon as I visit.
