My issue is that a number of useless and empty pages are being created, and I'm not sure why. When I generate a sitemap, I get a bunch of duplicate stuff with the same page title: "Technology Buyer's Advocate Forums". When I click on a link within the sitemap for these pages, I see the "Welcome Guest" login page.

Any idea what's causing this? This can't be good for SEO.

Thanks in advance for your help.

"Duplicate stuff" does not explain the situation. Please provide a few urls as examples.

http://www.technologybuyersadvocate.com/site_map.html 

Starting at Line 11 (the forum entries), click on any of the links to "Technology Buyer's Advocate Forums". These are the so-called "empty" links to which I refer.

This HTML sitemap came from an XML sitemap generator. These pages must have been created within YAF, but they have no "meat". Is there a way to avoid their creation?

BTW, I am running YAF version 1.9.1.8, on Windows Server, and .NET 3.5.

Thanks so much for your help.
