I went to the FAQ tab and did a search for poll. Here's what came up. Hope it helps.
You may notice that some threads on this forum also include a section where you can vote on an issue or question. These threads are called 'polls' and this is how to create them:
Creating a new poll
When you post a new thread, you may have the option to also create a poll.
This function allows you to ask a question and specify a number of possible responses. Other members will then be able to vote for the response they wish, and the results of the voting will be displayed in the thread.
An example poll might be:
To create a poll when you post a new thread, simply click the 'Yes! post a poll' checkbox at the bottom of the page, and set the number of possible responses you want to include.
What is your favorite color?
- Sky-blue pink with yellow spots
When you click the submit button, you will be taken to the poll creation page, where you can specify the question and the list of responses you want to include.
You may also want to specify a time limit for the poll, so that (for example) it only stays open for voting for a week.
Voting in and viewing a poll
To vote in a poll, simply select which option you want to vote for, and click the [Vote!] button. You may view the current results for a poll before you vote by clicking the 'View Results' link. Voting in a poll is entirely 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!
