This is how you create a poll...
At the bottom of the start a new thread page in the Additional Options section there is a checkbox that says "Post a Poll" with a "number of options" text box. You check the checkbox and enter the number of options you will want people to vote for. When you hit submit, it should take you to a screen to enter the options and then post your new thread.
I know in the New Forum Q&A, I believe, Kevin said there was a problem so when it is resolved the above will be how you add a poll.
