When you create a new thread, there should be an option, "post a poll with this thread". click it, and you can type in how many poll options you want. (up to ten).
youll have to click on "post new thread", but dont worry, a new window will appear where you type in what the poll options are. then, it will appear with the new thread. you can also pick other options for polls, like when it will close, public or private, etc.
or you could be lazy, and ask a mod to do it, although i dont think theyd like that
