When you start a new thread just page down a bit to additional options. You will see a post poll box (4th one down). click in the box yes and enter how many entries you want in your poll (up to 8). You have to put a title in the title box and some text in the message box (eg. a sentence about the poll). Then hit the submit new thread bar, this will give a new thread box where you can put each poll question in it's own box. You can also edit or add more text over the poll questions.
Hope this works for you, wil.
