An Internet forum, or message board, is an online discussion site. It is the modern equivalent of a traditional bulletin board, and a technological evolution of the dial-up bulletin board system. From a technological standpoint, forums or boards are web applications managing user-generated content.
People participating in an Internet forum can build bonds with each other and interest groups will easily form around a topic's discussion, subjects dealt within or around sections in the forum.
