Hyperlink two pages

Hi there,

I have 2 simple questions:

1. Is there is a posibility if I click on a hyperlink; then 2 pages will appear.

2. How can I pop up a page while I am opening a page.

this in the head:
function MM_openBrWindow(theURL,winName,features) { //v2.0
window.open(theURL,winName,features);
}

(remember the < , < -! thing and script language="JavaScript" tag, and end script tag )

this inside the body tag itself:
onLoad="MM_openBrWindow('http://some url.com','','toolbar=yes or no,location=yes or no ,status=yes or no ,menubar=yes or no ,scrollbars=yes or no ,resizable=yes or no')"

I hate pop ups by-the-way.
