The term chat room, or chatroom, is primarily used by mass media to describe any form of synchronous conferencing, occasionally even asynchronous conferencing. The term can thus mean any technology ranging from real-time online chat over instant messaging and online forums to fully immersive graphical social environments. A chat room is a Web site, part of a Web site, or part of an online service such as America Online, that provides a venue for communities of users with a common interest to communicate in real time. Forums and discussion groups, in comparison, allow users to post messages but don't have the capacity for interactive messaging. Most chat rooms don't require users to have any special software; those that do, such as Internet Relay Chat (IRC) allow users to download it from the Internet.Chat room users register for the chat room of their choice, choose a user name and password, and log into a particular room (most sites have multiple chat rooms). Inside the chat room, generally there is a list of the people currently online, who also are alerted that another person has entered the chat room. To chat, users type a message into a text box. The message is almost immediately visible in the larger communal message area and other users respond. Users can enter chat rooms and read messages without sending any, a practice known as lurking.
Because chat room messages are spontaneous and instantly visible, there is a potential for abuse, which may or may not be intentional. Site hosts typically post a frequently asked questions (FAQ) list to guide users to appropriate chat room behavior, such as introducing yourself when you enter a room, making it clear when you are directing a question or response to a specific user, and reporting disruptive users, for example. Disruptive users may verbally abuse other chatters, monopolize the conversation, or even just disable it by repeatedly typing the same word or phrase into the conversation, a practice (much frowned upon) known as scrolling.
Chat rooms can be found that focus on virtually any aspect of human endeavor or interest: there are current communities based on classic movies, Irish ancestry, baton twirling, and psychic readings, for example. Various sites, such as Yahoo, provide a directory of chat sites. Others, such as MSN Web Communities, guide users through the steps required to create their own chat room.

Flash Chat v4.8.2

FlashChat includes a set of advanced administrative options so that you can easily manage rooms, users, bans, messages, and much more.
The room list and message input area can be re-positioned to different parts of the screen by simply dragging and droppinig. These layout positions can also be set by default in the external layout file.
A PHP-based "bad words filter" allows you, the chat administrator, to prevent foul language from being viewed within the chat. FlashChat's text options can also be externally configured in the config.php file. You can add additional font sizes, specify the default font sizes for the interface text, set the default language, and much more!
Nearly every color in FlashChat can be modified within the PHP configuration files (using the HEX color code). You can also set custom JPG or SWF background images easily by editing the appropriate theme file, located in the /inc/themes/ folder).
FlashChat has the ability to use small, graphic avatars for any user. You may also set special avatars for administrators, or to distinguish male vs. female users. The background image can be customized for any user as well.
