Not to be confused with the current, trendy blog. A forum is a space where like minded individuals can contribute information of mutual benefit. A forum is a repository of data which is meant to inform and educate on a particular subject.
Forums generally are not conversational, rather, they are contributory.
An example of a forum is a Web site where dental hygenists may contribute information on technique, research, seminars and practicums, case studies, and all other manner of useful data.
