The OP is referring to Profile Comments, not Private Messages. There's a difference.
Slight hijack here: Actually, for Private Messages (PM), you can set a preference to have a new PM appear as a pop-up on your iRV2.com window when you have a new message. Not a flashing sign or noise, but if one has pop-ups enabled, that's one indicator (the other is an email notification) you have a new PM.
