BuddyPress.org

Hi I’am using “buddypress” and the “BuddyPress Group Email Subscription” plugin to send emails to members whenever a group activity is done. Those emails are per default send to all members of the group (identified by their user id in the source code).

Each underaged member has also a custom field with a separate email address for his father or mother. The parents are no users/members in the System.

So, how can I achieve that group activity email will also be send to the email addresses stored in the costume filed?
