This plugin allows you to use the shortcode [copyright], which inserts a copyright symbol, the site name (linking back to the homepage), and the year.
A span with the class “copyright” wraps this, and the year is dynamically updated.
This is ideally used in the footer of your website. If shortcodes don’t work in widget areas on your site, check the FAQs.
