When you enable the plugin, a new button will appear on all blog post and topic discussion pages, "Subscribe". If you click the button, it will change to "Unsubscribe" and another button will appear, "Show subscribers". If you click on the Show subscribers button, a pop-up window will appear with the profile icons and names of all users who are currently subscribed to that blog postor topic discussion. You will receive a message from the Elgg system when someone comments on the blog post or replies to the topic discussion. If you're not interested in the post or topic any more, just click on the "Unsubscribe" button. If a post or topic already has subscribers, you'll see the Show subscribers button even if you are not a subscriber.
