A message board generally consists of a number of specific discussion topics, each with numerous messages written by users. Message Boards represent a huge community of web users, and a place to discuss, debate, and make new friends.
People use message boards for a variety of reasons.
Some people use them to discuss subjects of interest to them, to meet new people and find folks with similar interests. You can use message boards to seek romance, business advice, or just to pass the time. As a form of communication, message boards fall somewhere between a personal email and an announcement over the radio. Be smart and use common sense precautions when posting. Don't give out your phone number or address.
