WACKOs, Super WACKOs and Saints may create polls. Any registered user can vote in a poll. Before you create a poll, write it out on a piece of paper. Carefully word your question so that it is 'neutral' in language and clearly states what you want to find out.
Make sure you have a complete set of possible answer choices. This system does not allow write in answers so you should probably include choices such as "More than one of the above" or "All of the above" or "None of the Above" or "Another Choice".
