Forum:CSS/JS to make "Talk Page" Notifications on pages

Can someone tell me the CSS/JS that I would use to make a notification saying "You have a new message" for a page that isn't User talk. It is a personal talk page on a wiki where Message Walls are enabled. If you need the page; it is located here. I'd very much appreciate help :] Thanks :] -- 21:17, July 6, 2012 (UTC)
