Add the ability for users to follow others and keep track of their site activity. This plugin works exactly the same way that the friends component of BuddyPress works, however the connection does not need to be accepted by the person being followed.
To enable the follow capability, the BuddyPress Followers is required. The plugin is available for free in wordpress.org repository. You can download it or install directly from the WP admin panel › Plugins › Add new panel.
