Hi Pah,
Welcome to TOTV! Your best bet probably is to get a guest pass when you come down.
"Post a poll," is a feature of TOTV that lets you pose a poll question. If you had responded, yes, that you wanted to include a poll when you started this thread, it would have walked you through set up. You can set up yes or no answers or give people a range of choices. Responders click a button next to the their answer, and the answers are automatically tabulated.
For example, here is an example of a thread that includes a poll:
