With a registration form, participants register for a meeting. You prepare the forms here, and meeting organizers choose one when they schedule a meeting.
You find “Meeting registration forms” under “Account settings” in the left hand side navigation. To create a form, click on the “Add” button in the upper right hand side corner.
The next screen is “Configure your registration form”. A new form already asks for the first name, the last name and the email address.

You can choose to set a registration form as default by selecting the “heart” icon behind a form. The default is preset when a meeting organizer schedules a new meeting. Choose “No meeting registration form” as default if new meetings should have none.
To delete forms, select the check box(es) in front of them and click on the red “Delete selected forms” button in the top right corner.
Here you prepare polls for your whole account. Meeting organizers can add them to a meeting when they schedule it, next to their own polls.
You find “Polls” under “Account settings” in the left hand side navigation. To create a poll, click on the “Add” button in the upper right hand side corner.
To delete polls, select the check box(es) in front of them and click on the red “Delete selected polls” button.

How polls work during a meeting is described in the meeting organizer hand book.
