when you Create a New Thread there is a section "Additional Options" beneath the normal part where you can type in your post - see attached image.
Check the box to create a poll (highlighted in red in my example)
Select the number of poll options you want (up to 10)
Click on Submit New Thread and you will be taken to the screen where you enter your poll options and so on.
NOTE: When you click on Submit New Thread the text part of your post will appear on the boards but the poll will not appear until you have finished typing in the options. I suggest you have a clear idea of what you want to put in the poll options before you even start the thread because if you spend a long time creating the poll bit people will just see the ordinary post part on the board with no associated poll while you are editing that.
