The open poll will appear in the 'Open Surveys & Polls' tab. You can click on the poll icon to start responding to the poll.
You can then answer or skip the questions that make up the poll. When you have responded to all the questions you will see a 'Submit' button become available. Clicking on 'Submit' will send your response.
