*requirements: basic knowlagde on html so u can edit your messeges

this goes in <head>
Code:
<SCRIPT LANGUAGE="JavaScript">

<!--

var speed = 50 // decrease value to increase speed (must be positive)

var pause = 2000 // increase value to increase pause

var timerID = null

var bannerRunning = false

var ar = new Array()

ar[0] = "MESSAGE #1"

ar[1] = "MESSAGE #2"

ar[2] = "MESSAGE #3"

ar[3] = "MESSAGE #4"



var currentMessage = 0

var offset = 0

function stopBanner() {

        if (bannerRunning)

                clearTimeout(timerID)

        bannerRunning = false

}

function startBanner() {

        stopBanner()

        showBanner()

}

function showBanner() {

        var text = ar[currentMessage]

        if (offset < text.length) {

                if (text.charAt(offset) == " ")

                        offset++

                var partialMessage = text.substring(0, offset + 1)

                window.status = partialMessage

                offset++

                timerID = setTimeout("showBanner()", speed)

                bannerRunning = true

        } else {

                offset = 0

                currentMessage++

                if (currentMessage == ar.length)

                        currentMessage = 0

                timerID = setTimeout("showBanner()", pause)

                bannerRunning = true

        }

}

// -->

</SCRIPT>
and except of writing <body>
u should write:
Code:
<body onLoad="startBanner()">
enjoy...
