There have been no specific rules or guidelines for holding a town hall meeting. The format of the meetings can vary. Usually, the person holding the meeting (e.g. member of Congress) makes some opening remarks. Sometimes others (e.g. local leaders) will address the audience, as well. The main part of a town hall meeting tends to occur when the floor is opened up to questions and comments from the audience. Attendees generally present ideas, voice their opinions, ask questions of the public figures, elected officials, or political candidates at the town hall. Sometimes, the town hall meeting is televised or recorded. In recent years, town halls held by political candidates have announced and enforced rules on crowd behavior and the scope of questions that may be asked.
