Frames info update
 

Even though most, if not all, major search engines now index frames and even with the use of the NOFRAMES tag you run the risk of your pages being displayed in the search engine results out of context. As each individual page is indexed separately, it is likely that your website visitors will not see your pages within your frame and will effectively be stuck on the page they arrive at.
If you must use frames then create a 'Home' link on each of your individual content pages and point the link at your frameset index page.
