Groups

Groups, also referred to as forums and sometimes newsgroups, have been around almost since the dawn of the Internet. They were originally developed so that scientists could post questions (and answers) to each other. Today, groups resemble bulletin boards, where people discuss subjects of mutual interest by posting comments. Groups revolve around specific topics, such as wireless technology or organic food. You can read what others have written and add your own thoughts.
