Blogroll Forums NoFollow URL

The only way that you could get to a page was if you knew the URL, or followed a link from another page. We allow links in the comments, but we nofollow them so no link juice escapes. We’ll put the odd blog in our blogroll, if we even have one. Each page contained hyperlinks that referenced other pages that were relevant.
