To vote in a poll, simply select the option you want to vote for, and click the [Vote!] button.
You can view the current results for a poll before you vote by clicking the "View Results" link. Voting in a poll is optional. You may vote for any of the available options, or cast no vote at all.
Generally, once you have voted in a poll, you will not be able to change your vote later, so place your vote carefully.
