I am looking for a DHTML popup script. I want to have a small popup box come up on my site and ask the visitor to join the newsletter but I don't want to have any window edges. I want it to look like an image where they can enter their email address and subscribe. Any ideas?

// javascript popup sizeable window
function NewWindow(mypage, myname, w, h, scrolling) {
var winl = (screen.width - w) / 2;
var wint = (screen.height - h) / 2;
winprops = 'height='+ h +',width='+ w +',top='+ wint +',left='+ winl +',scrollbars='+ scrolling +',resizable='+'no'+',menubar='+'no'
win = window.open(mypage, myname, winprops)
if (parseInt(navigator.appVersion) >= 4) { win.window.focus(); }
}

  <a href="page.xxx" onClick="NewWindow(this.href,'name','330','350','no');return false;">Anchor Text</a>
