PM message pop-up

Most forums have the facility to set a preference for getting a pop-up if you get a private message. Like this one, most have it switched off by default. Not a facility I've used often, so I tend not to spot any message. So if needed you can set it like this....
Profile>>Preferences>>Display a pop-up window for new private messages – set to “yes"

Thanks for this, Steve. Have changed mine now.
