As the listing agent, you can select which internet sites/consumer portals you want your listing syndicated to during listing input/edit:
Pull up the listing through Add/Edit, click on the data input form, go to the Additional Info tab and use the check boxes in the Display on These Websites field to select where you would like your listing sent:
Note: if you select to send your listing to one of these sites but your broker chooses not to send any of your office's listings to that site, your listing will not display on that site. The broker's/office's selection supersedes the list agent's. Both the agent and office must authorize syndication to a site in order for the listing to be in that particular data feed.
Click Submit Listing when you're done.
