first of all...im gonna move ur thread to feedback forum..coz u should post all such queries over there...then hang in there..i would try to help u how to start a poll
when u start a new thread.then a page appears where u type ur stuff..on the very page scroll down and uL find the option to start a poll Ok..i have attached an image...take a look at the bottom of image the red mark part
adding to wht vini said...if u have already crated a thread and later want to add a poll then go to thread tools and select "add poll" option
