Out of the box, a custom WordPress install does not have a way that your readers can SUBSCRIBE to your blog. That is where RUA Blog Subscriber comes in. Our plugin allows for your readers to subscribe to your blog. That do not have to create an account to your WordPress website. For more detailed information, go to RUA Blog Subscriber Website. If this plugin is something you need, come back here to the Shop and purchase. If you could use the plugin but do not need all of the extra customization, then go grab the Free Lite version.
