I've published a poll but it doesn't display on the web site?
For a poll to display it must be published within a group, with a layout
applied to it that contains a poll component, or you need to have a poll module within the template
you are wanting to use.
For example the display a poll on the frontpage of your web site you would need to publish the poll in the contact database (root group) folder and have a poll component on the homepage layout.
Another reason for a poll not displaying would be if it's publish dates have expired.
