I just did my first one today that no one is responding to.
1. Click on the "New Thread" button.
2. Enter your title and text for your new thread. Scroll down. There is a box called "Additional Options." The last option (of 4) is called "Post a Poll." Check off "Yes, post a poll with this thread."
3. Click on the "Submit New Thread" button. This will take you to a whole new screen that lets you customize your poll--question name, choices, multiple choice, expiration date on the poll, etc.
4. Once you do all of that, then click on "Submit New Poll" or "Preview Poll" depending on what you want to do.
I hope I was helpful.
