@dtmaddog71, Slido is included with Webex so no additional purchase is needed. In the new Webex Suite, it has replaced the legacy Q&A feature. Additional features include polling as well. If you have a Cisco Webex host meeting license, you can go to www.slido.com and when you click Sign In, you'll select Sign in with Webex. If you have more questions regarding it's compliance with the 889 regulation, you would need to reach out to your Cisco Account Representative.
