A survey is a content type which allows you to collect information from participants in your zeeting.
To add a survey, follow these quick steps:
Select "Add Content"
Select "Create a survey"
Choose which field you would like to ask participants to complete. Surveys can ask for up to three fields of information: name, email and a free text question that you can define. You don't have to use all the fields so may, for example, just ask participants for their name and email address.
Here's a quick video walking you through Surveys.
There is some overlap between surveys and requiring participants to provide information when joining a Zeeting (you can learn more about the latter here). Use a survey when you do not want to make entering information the first thing that happens when a participant joins or if you want to also ask for additional information such as feedback on your presentation.
