Comment on SEO Silo Theme by Carl Bradbrook.
Im on the css at moment and will come back to this and test.
I did up load the new files in zip from that post so widget should work fine.
Will let yuou know how i go on this :-)
I guess it would be easier to use the custom menu when you have that ready as I can use drop down menus in that as it wont be seo value much as most of the page will be protected content.
