How do I edit or delete a poll?As with posts, polls can only be edited by the original poster, a moderator or an administrator. To edit a poll, click to edit the first post in the topic; this always has the poll associated with it. If no one has cast a vote, users can delete the poll or edit any poll option. However, if members have already placed votes, only moderators or administrators can edit or delete it. This prevents the poll's options from being changed mid-way through a poll.
