Start Webpage in certain area

Start Webpage in certain area

Looking for a script that will start a website at a custom location (ie. www.yoursite.com starts page at top: 800px, left: 400px) I am NOT looking for any sort of popup window positioning. When a visitor access the site using their browser I want that page to start at a location I specify like this website does: http://volll.com/ -- Please note, I realize this site uses anchor tags to accomplish this. I'm not good enough at Jquery to know how they did it, or modify it so that it also handles points left as well as top.

The ideal script would position this point in the center of the browser window.

Any ideas? Tips? Places to look? I'm new so if there is a step by step tutorial...
