All WordPress based blogger might have come across ‘Subscribe to Comments’ plugin atleast once. It provides an option to the commentators to receive email of any future comments on that post. This plugin is helpful, both for the blog owner and commentator.
As shown on the image, once a commentator checks the “Notify me of follow up comments” he/she will be informed via email of all future comments on that post. Unlike previously, now WordPress blogger need not install this plugin separately as the WordPress blog says “There are no switches to pull or buttons to push to switch it on. It’s already enabled on all blogs”. So, if you are a blogger hosted on WordPress then forget the hassles to install this plugin, and if you are a commentator then you too have a advantage of not visiting a blog again and again checking for replies. Just subscribe to comments and forget it. 🙂
