Hybrid Byline

Hybrid Byline is a plugin that adds a frontend interface to the Hybrid Settings page for users of the Hybrid theme to change the byline settings.

By default, the plugin reflects the existing byline settings that Hybrid uses. It gives you the ability to add categories or the number of comments to your post byline. You can add the author and date to pages as well. One extra
addition is that you can choose to add nofollow to the post author link (a possible SEO benefit).
