I got to the bit where it wanted me to edit the poll and set it up, looked at the options there and said 'ah, ok, that's how it works' and bailed out. It's weird how it does the post separately from the poll.
It takes time. When you create a poll, your thread is posted, THEN you create the poll. So if you have lots of text to insert, and/or a lot of options, the poll may not be visible for a while.
