After your Broker In Charge has completed the step to setup Broker Attribution for your office, navigate to my.doorifymls.com and click the Listing Manager tile on the Dashboard.  

Click "Menu".

Select "General Preferences".

Click the "Broker Attribution" tab.

Enable “Make Broker Attribution Active”.

Click the "Enter e-mail or phone number" field and add the default email or phone number for listings. This default number or email will appear on listings if the Listing agent does not update the Broker Attribution phone number or email on the individual listings. Then click "Save".
