Visual chat rooms add graphics to the chat experience, in either 2D or 3D (employing virtual reality technology).
Some online chat rooms also incorporate audio and video communications, so that users may actually see and hear each other. These are typically implemented by an external process such as an IRC bot joining the room to conduct the game. Chat rooms, particularly those intended for children, usually have rules that they require users to follow.
The rules are generally posted before entry, either on a web page or an MOTD-type banner in the case of IRC and other text-based chat systems.
