Welcome to the Q&A Forum

Hi BJ, From an SEO point of view i don't like to work in AJAX but it sure has some user experience points, doesnt it. Have you read this article http://www.seomoz.org/blog/create-crawlable-link-friendly-ajax-websites-using-pushstate. Common practise is to check the text cache of the site, that way you are able to see what the search engine see's and possibly see where your dulicate content issues are

OK thanks Alan. I used OSE and just sorted pages with links and set up 301's and will let the rest 404.

Thanks James, Champion!

Thanks mate! All i wanted to know.
