replace your ??????? with *

Can you try replacing your GetXmlHttpObject function with this one?

function GetXmlHttpObject(handler)
var xmlHttp=null;
if (window.XMLHttpRequest)
//code for IE7+, Firefox, Chrome, Opera, Safari
xmlHttp = new XMLHttpRequest();
} else if (window.ActiveXObject) {
//code for IE6, IE5
xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {alert (e.description);}
return xmlHttp;

Does your page members.php have some code that checks the session variable is set? If so can you post that code?

Use javascript

screen.width - gives you the screen width
screen.height - gives you the screen height

window.resizeTo(600,600); - resizes the window

I hope that was quick enough for your needs, however this info took me 2 minutes to find using google.

There is no CSS solution to this problem
Your answer lies in javascript

This site should help you out

Unfortunately, textarea doesn't support maxlength.
You can use javascript to limit the length

Are you familiar with jQuery?
