No matter where you're at on FQuick, you will get a visual indicator notifying you of a new message. If you are anywhere on the site, minus garages or user vehicle pages, you will receive notification both on your left user navigation pane as well as the "Messages" tab lighting up red.
If you are in someone's garage or looking at one of their vehicles, your "Messages" tab will still light up red to notify you of a new message.
Please use the Contact Form if you have already tried that and were unsuccessful.
