 *
 * Send an email all users who have submitted Form A when Form B is submitted. This *should not* be used
 * to large numbers of notifications.
 *
 * # Instructions
 *
 * These instructions assume that Form A contains an Email field.
 *
 * 1. Add a Hidden field to Form B.
 * 2. Enable "Populate value dynamically" setting and configure settings (https://gwiz.io/2LgCdZS):
 *    - Type: Gravity Forms Entry
 *    - Form: Select Form A.
 *    - Value Templates / Value: Select Email field.
 * 3. Create a new notification.
 * 4. Set the Sent To / Send to Email value as the merge tag for the Hidden field we added in Step 1 (https://gwiz.io/2CfXccB).
 *
 * That's it. Populate Anything combined with this snippet will populate a comma-delimited list of emails in to the Hidden
 * field. This snippet will parse the comma-delimited list and send a separate copy of the notification to each email.
