Conversation threading is a feature used by many
email clients,
bulletin boards,
newsgroups, and
Internet forums in which the software aids the user by visually grouping messages with their replies. These groups are called a
conversation,
topic thread, or simply a
thread. A discussion forum,
e-mail client or
news client is said to have a "conversation view", "threaded topics" or a "threaded mode" if messages can be grouped in this manner.
