 How do I create a poll?
Creating a poll is easy -- when you post a new topic (or edit the first post of a topic, if you have permission) you should see a Add Poll form below the main posting box. If you cannot see this then you probably do not have rights to create polls. You should enter a title for the poll and then at least two options -- to set an option type in the poll question and click the Add option button. You can also set a time limit for the poll, 0 being an infinite amount. There will be a limit to the number of options you can list, which is set by the board administrator
 How do I edit or delete a poll?
As with posts, polls can only be edited by the original poster, a moderator, or board administrator. To edit a poll, click the first post in the topic, which always has the poll associated with it. If no one has cast a vote then users can delete the poll or edit any poll option. However, if people have already placed votes only moderators or administrators can edit or delete it; this is to prevent people rigging polls by changing options mid-way through a poll
