When you start a new thread scroll down past the first create button and you should see a Poll section. Once you select your different options, you can then select create. Here is a screenshot of what it looks like. Try it out in the test section of the Forum Business.
J Grant I would suggest experimenting with one in the water cooler so see how it will appear, the number of responses, public or private, how people voted, etc. Then post the real one. You could practice with a non-controversial topic like climate change or people who eat fried, dead animals....there are a few in here who are guilty. Of course I'm assuming you're going to post something appraiser related for the real poll?
