If you would like to add a co-list agent or homeowner to your listing (so they can get ShowingTime notifications):
Log into ShowingTime- either from the icon in the Quick Links section of the SmartMLS Member Dashboard or by clicking ShowingTime in the External Links widget on the Matrix homepage.
Go to Listing Setup and select the desired listing.
Go to the Contacts section and click on either of the buttons in the bottom right:
Once they are added, you can choose how and when they receive appointment notifications.
