If you did use frames, you wouldn't need to redesign your page, it's just the same as the lunarforums!
You don't see the names of the actual pages, you just get
www.lunarforums.com at the top (unless you open a link in a new window).
It's just this code in the first page (index.html or whatever)
<HTML>
<HEAD>
<TITLE>Lunar Forums</TITLE>
<SCRIPT>
<!--
if(top!=self)
top.location.href=self.location.href;

Click <a href="yourmainpage.htm">here</a> to enter the whatever your site is called.
