allows you to ask for more information from you participants than just their name and their availability. You can ask for their email address, their phone number and/or their address.
Using this feature can have several upsides. First of all asking personal details from a participant suggest that participating in a poll is binding. It can make a poll work as a registration system that helps you gather information from your participants you do not already have.
To enable this feature on your poll just mark the checkboxes in the settings screen, accessible in step 2 on poll creation.
After your participants have entered their name and their availability they will have to answer with the details you required before their response is saved to your poll.
The poll must be exported to Excel to view the collected user data.
Open the admin link and click on the top menu 'More' and then on 'Export to Excel'.
