An online based forum is also known as a message board and is a form of online discussion or conversation between the websites users. A forum allows online users to post messages and read other posts from individuals on a subject matter of interest to them. On a forum, the messages posted on the forum page are archived for a certain period of time to allow readers to view the posts at a later date. Some forums apply a moderator to verify the content of the messages before they can be posted online.
