IWeb and MobileMe Help

I have a website that I made thru iweb and use mobileme to host. Problem is that iweb extends the url name with backslashes and site names.

For example, my website is http://www.patrickseankennedy.com

I want the homepage url to stay "http://www.patrickseankennedy.com" but with iWeb adding the site name "psk" and the home page name Patrick Sean Kennedy Video Production, I get some backslahsed mess such as "http://www.patrickseankennedy.com/psk/Patrick_Sean_Kennedy_Video_Production.html"

Does anyone know what I am doing wrong here and can help clean up this mess?

Any help would be appreciated...
