Go to FAQ section and click on FAQ.
In the search box type "start a poll."
Scroll down to the bottom of that page once it opens up, and read the different links and answers to the question how do you start a poll, specifically by reading the "Thread Tools" section, then read, "Starting A Poll." Click on underlined section stating, "Click here for more information on polls," then work,your way through the page that opens up.
NOTE: Starting a poll can be tricky, so please read, and re-read that section several times before you start and create your first poll. After messing up the first time I tried to create a poll, I screen-printed that page on how to create a poll, then on my second try, by working my way through my screen-print line by line, I was able to successfully to do it. As I was able to create a poll, you can too.
