These are typically implemented by an external process such as an IRC bot joining the room to conduct the game. 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.
Saying a nice greeting to everyone is the best way to catch someone's attention.
The users in a particular chat room are generally connected via a shared internet or other similar connection, and chat rooms exist catering for a wide range of subjects.
New technology has enabled the use of file sharing and webcam to be included in some programs. The first online chat system was called Talkomatic, created by Doug Brown and David R.
Talkomatic was very popular among PLATO users into the mid-1980s.
In 2014 Brown and Woolley released a web-based version of Talkomatic.
