Open your poll directly from your dashboard or by using the admin link. Click the 'more' menu at the top of the page. Click 'choose final option.' It might also be located directly on the black bar.
You'll notice that Doodle will suggest the most popular option in the poll with the gold star. You can choose this option, or any other option, and the click 'done.' If you have your calendar connected, and have synchronization turned on, the final option will automatically appear in your calendar.
Now you can inform your participants about your choice. If you invited your participants via email from Doodle, they will automatically appear in the "share results via" field. If they have subscribed to updates on the poll, they will receive an automatic notification per email as well.
A closed poll can be reopened at any time by the administrator under the "more" menu.
