Under Preferences > Portal Preferences you will find all of your settings related to lead management.
You can also search for 'Portal Preferences' in the menu:
Each link you create in your IDX Manager has a list of options of when to require the user to sign-up or sign-in to your flexmls portal. When editing an IDX link, go to Step #4: “Portal Registration”.
If you check the last option, “Allow visitors to skip the above registration options”, the registration pop-up window will add a “Maybe Later” button and allow the user to continue browsing listings.
You can require the address and phone number fields by going to Menu>Preferences>Portal Preferences>IDX Lead Generation in the flexmls system. Under Required Fields check the address and/or Phone Number, scroll to the bottom of the page and click on “Save”.
