Filter recipients of forum and topic subscription email messages.

[roysmyth]

I would like to be able to filter the recipients of forum and topic subscription email messages.

Adding filters in bbpress/includes/common/functions.php after lines 1105 and 1245 to filter the array of user ids should do it.

Something like
$user_ids = apply_filters( ‘bbp_forum_subscription_mail_ids’, $user_ids );
and
$user_ids = apply_filters( ‘bbp_topic_subscription_mail_ids’, $user_ids );

For context via bbpress.org

If a user who has capability “participate” subscribes to a forum and then is demoted to capability “spectate”, will the user continue to receive notifications?

I run a membership site. When membership expires, the user continues to be a member but with limited capabilities. I want the user to stop receiving subscription notifications

Thanks for creating the ticket.
