if you already have the code to rotate the message through, you can just use [tt]window.status=someString[/tt] or you can use [tt]self.status=someString[/tt] (like what jaredn said).
if you don't already have the code for it, javascript.internet.com has some great status bar messengers.
but remember, don't get to obsessed with the status bar, because it can get very annoying.
