Group Forum Subscripton for BuddyPress

** Use of this plugin is not recommended in versions of BuddyPress 1.2 and higher. Please consider using BuddyPress Group Activity Notifications instead: https://wordpress.org/extend/plugins/buddypress-group-activity-stream-subscription/. A conversion script for converting subscription data from this plugin to that one is coming soon **

Features:

Users can subscribe to discussions on a group-by-group basis;
Users are automatically unsubscribed from a group』s discussions when they leave the group;
Administrators can subscribe all users to the appropriate forums with a single click (potentially handy for first-time setup);
Administrators can toggle whether email notification is turned on by default;
Administrators can toggle whether posters receive notification of their own posts.

Running BP < 1.1?

If you plan on having your members use the bbPress interface in addition to/instead of the BuddyPress forums interface (something you can only do if you are running bbPress in a separate installation, which means you』re almost certainly running BP < 1.1) do the following steps as well:

• Upload bb-group-forum-subscription to [bbpress-directory]/my-plugins
• Activate the plugin on the bbPress admin page
  In [bbpress-template-directory]/topic.php, replace the code
  user_favorites_link();
  with
  user_favorites_link( array(『mid』 => __(『Subscribe to this discussion』)),array(『mid』 => __(『Unsubscribe from this discussion』)));
