In case you're using Disqus Comment System on your WordPress blog, you've lost the comment notification feature that is normally present in WordPress: in other words, when someone comments on a post/page by author A, author A should get an email notification about the comment. When using Disqus however, only Disqus comment moderators get notified of comments to posts/pages.
This plugin fixes that problem by notifying authors of comments to their posts/pages regardless of whether or not they are comment moderators on Disqus.
To use this plugin, search in your WordPress plugins installation for disqus notify (or simply go to this url: <your-wp-site>/wp-admin/plugin-install.php?tab=search&s=disqus+notify) and simply install it.
Alternatively you can head over to the WordPress.org page of this plugin.
