Polls allow your users or visitors to submit there opinion on a given question and see the results as a percentage of answers submitted.
The results are kept inside a SharePoint list allowing you to view them easily. A user selects the answer they need, submits the response
and then views the answer in a small bar chart with percentages (fully configurable by editors). Results are totalled in the underlying
list allowing you to see the responses for all your configured polls, current and historic, easily.
See the tutorial to see just how easy they are to configure.
