I need a scrolling text that will load the text  from a text file (.txt), so that the users will be able to change the text regularly. Maybe with an option of having some of the text link to another page. Thanks

A small demonstration with Ajax. Designed to run locally. Please do a further study to adapt to your environment. Here is the code:

<html>
	<head>
		<title>Script Demo Gops</title>
		<script language="javascript">
			function ajaxpage(url, containerid){
				var page_request = false
				if (window.XMLHttpRequest) // if Mozilla, Safari etc
					  page_request = new XMLHttpRequest()
				else if (window.ActiveXObject){ // if IE
					  try {
							page_request = new ActiveXObject("Msxml2.XMLHTTP")
					  }catch (e){
							try{
								  page_request = new ActiveXObject("Microsoft.XMLHTTP")
							}catch (e){}
					  }
				} else return false
 
 
				page_request.onreadystatechange=function(){
					  loadpage(page_request, containerid)
				}
 
				page_request.open('GET', url, true)
				page_request.send(null)
			}
 
			function loadpage(page_request, containerid){
				if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
				document.getElementById(containerid).innerHTML=page_request.responseText
			}
 
			window.onload=function(){
				ajaxpage('marque.txt', 'mar');
			}
		</script>
	</head>
	<body topmargin="0" leftmargin="0" marginwidth="0" marginheight="0">
		<marquee style="position:absolute;left:100px;margin-top:100px;background-color:grey;width:200px;height:15px;font-family:verdana;font-size:11px;" scrolldelay="1000" id="mar">aaaa</marquee>
	</body>
</html>

You can type anything. Here is what I have:
marque.txt:
"This would be so slow, you'd get no sense of animation."
