Turn-based role-playing is the act of role-playing with a certain posting order. In the strictest sense of the term, it means that a role-player participating in a turn-based role-play will only post after each of his or her fellow players have posted. Sometimes, however, the rules may only be as limited as frowning upon double-posting. Most forum and other board role-playing is turn-based. For chat room role-playing, it depends on the preference of the participants or the decision of the game master.
