A forum, in the context of the internet[3], is a virtual platform designed for public discussion. Evolving from bulletin boards and computer[4] conferencing systems, forums are structured like a tree, with categories, sub-forums, and threads. These online sites host messages posted by users in conversational threads. Unlike chat room[2] messages, forum posts are typically longer and can be archived for future reference. Forums often require user registration for posting messages but generally allow open access for reading them. They cover a broad spectrum of topics, from tech to entertainment, fostering a virtual community[1] among users. Key roles within a forum include administrators, who handle technicalities and appoint moderators, and moderators, who manage discussions and user concerns. Forums also exhibit certain behavior patterns, including open discussions, conflicts, trolling, and spamming[5]. Technical features range from file attachments and emoticons to private messages and forum subscriptions. Forums may face lawsuits for libel and damage, with unique features and cultural usage differences across regions.
An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages. They differ from chat rooms in that messages are often longer than one line of text, and are at least temporarily archived. Also, depending on the access level of a user or the forum set-up, a posted message might need to be approved by a moderator before it becomes publicly visible.
Forums have a specific set of jargon associated with them; for example, a single conversation is called a "thread", or topic.
A discussion forum is hierarchical or tree-like in structure; a forum can contain a number of subforums, each of which may have several topics. Within a forum's topic, each new discussion started is called a thread and can be replied to by as many people as they so wish.
Depending on the forum's settings, users can be anonymous or have to register with the forum and then subsequently log in to post messages. On most forums, users do not have to log in to read existing messages.
