On our current company internal Web site, we have an announcement list on almost every section of the site. What I want to be able to do is have a "New Announcement Alert" on the home page (the only example I can think of is Facebook status updates). When a new announcement is posted on say the HR's department page, I want a little notice/alert to show up on the main home page letting our employees know that a new announcement has been added to that page. I want everyone to stay informed with every department in our company, but I don't expect them to visit every page of the site every morning to see what's new. Any suggestions??

Thanks so much!!
