I copied the example in the documentation to display
{exp:comment:notification_links}
{if subscribed}
<h5><a href="http://{unsubscribe_link}">Unsubscribe to comment notification for this entry.</a></h5>
<p> {if:else}<br />
</p><h5><a href="http://{subscribe_link}">Subscribe to comment notification for this entry.</a></h5>
<p> {/if}<br />
{/exp:comment:notification_links}However, nothing is outputted.
Is this supposed to be inside a {exp:comment:entries} or {exp:channel:entries} tag?
