Chat room users communicate through text-based messaging. Most chat room providers are similar and include an input box, a message window, and a participant list. The input box is where users can type their text-based message to be sent to the providing server. The server will then transmit the message to the computers of anyone in the chat room so that it can be displayed in the message window. The message window allows the conversation to be tracked and usually places a time stamp once the message is posted. There is usually a list of the users who are currently in the room, so that people can see who is in their virtual community.
