You can opt to Accept questions for the meeting presenter while creating your meeting or event. If you didn't initially set up your meeting/event to accept questions, you can change this setting with a quick edit.
Locate your meeting or event on the Meetings & Offline tab.
Click the drop down menu (the circle with 3 dots ⋯) to the right of your meeting/event and select Edit.
The Edit Settings window will appear. Scroll down to the Public Appearance (Online) section.
Accept Questions for the meeting presenter is set to Never by default. To change this, click the drop down menu and choose when you'd like to start collecting questions.
👉Note: Participants will only be able to submit their questions within the window you specify. For example, they will not be able to submit questions 3 weeks prior to the meeting, unless your meeting is set to Always accept questions.
A comment box will appear below the meeting wherever the meeting is published (e.g. visible on your hub and/or project page) during the specified time frame. For example, if you choose to begin collecting questions TwoDaysBefore the meeting/event, the comment box for questions would not appear until 2 days before.
Here's what it looks like on a project page:
Questions for the presenter will populate as comments below the meeting on the project page, as well as in the Comments tab under the meeting/event in the associated project.
If you feel a question is not relevant to the meeting, you can hide that question on the Comments tab. Learn more about Comment admin options and actions here.
