When adding new agents to your team, you'll simply add them to your Brivity CRM to get them to show on your Brivity IDX website. And Admin or the agent themselves be able to control what photo and contact info show on the site from the information in the agent's Brivity Profile.
However, when you remove users from your CRM, it currently is not dynamic to remove them from your website.
Step 1: In your Brivity IDX Builder, click on your name in the upper right, and click Account Settings.
Step 2: In the Roster Settings tab, check (to show on site) or uncheck any user (to hide from site).
Step 3: Click Update Roster Settings at the bottom. That's it!
