Install the plugin using the Extension Manager and the download URL above, which points to latest version of the plugin. Refer to Plugins on how to install plugins manually.
After installation you need to put the subscribe icon into your template's main.php
:
<?php $quicksubscribe = plugin_load('helper', 'quicksubscribe'); $quicksubscribe->tpl_subscribe(); ?>
The sprintdoc Template has built in support for this plugin.
The icon shows your current subscription status: If the icon is grey, you are not subscribed, otherwise you are. By clicking on the icon, you open a popup which either subscribes you to the current namespace or shows the current subscription and allows to delete it. Moreover, a link to the subscription manage page is given.
