Open the Meal Train page and click the Make Changes* button followed by the Edit Details button.
The street address line is optional. Should you choose to leave it blank, it will be replaced by a message to "Contact the organizer for the address". Then others could email you for more information. In addition, each time someone signs up for a date, you as the organizer will be notified and you could reply to that email with the address of the recipient. Also note that if the street address line is not included the Google Map icon will not be available to users.
