@ Mark - your robots.txt looks good, should be just a matter of time for it to clean up the index. Also make sure your Terms and Privacy pages are NOT included in your xml sitemap. Oh, and be careful with trying to "force" pages out of the index.

@ Will - what Tony reported here is simply wrong unless he looked at DNN 3 or earlier. It used to be that the Terms and Privacy Urls where uniquely generated depending on the page you were on and thus creating a mess of duplicate content. But that has been fixed a whole while ago (somewhere in the early days of 4.x if I remember correctly) and now you get ONE Terms and Privacy Url regardless of where you are on the site:

/Home/tabid/36/ctl/Terms/Default.aspx

/Home/tabid/36/ctl/Privacy/Default.aspx

for most default installations. And again, these two pages you should simply disallow in robots.txt. Tony is right in regards to "nofollow" though and I belive Bruce Chapman has "fixed" the Terms and Privacy skin objects and submitted to Gemini for consideration.

 Rod - I would simply create a conventional DNN page for the Terms and Privacy upon which you have full control over the Url with Url Master.
