The notification box in the FOMO plugin is a great way to increase the visibility of your website or blog. It allows you to display a message to your visitors that will notify them of new content or updates on your site. This can be a great way to keep your readers engaged and coming back for more. To use the notification box, simply go to the settings page for the plugin and select 'Notification Box' from the list of options. From here, you can enter the text that you would like to display in the box, as well as select the location on your site where you would like it to appear.
