This plugin is for bloggers who are concerned about the SEO impact of allowing comment author links on their posts.
While WordPress by default applies the nofollow attribute to such links, which was thought to preserve link juice for the original site, recently Google announced a change in the PageRank algorithm.
It also contains code for Thesis theme users to remove the redundant link on comment avatars.
The plugin does not use jQuery, but the Prototype library, which adds 38K to the page.
The library is delivered using the Google content delivery network, which optimizes geographic delivery and has excellent compression and caching settings.
Unpack and upload it to the /wp-content/plugins/ directory.
Activate the plugin through the 'Plugins' menu in WordPress.
