Chat rooms are scripts that allow any number of logged-in users to have a typed, real-time, on-line conversation. There are several pre-installed chat scripts available:
Entropy Chat – a simple chat script that offers basic features.
Melange Chat System – a Java chat script that offers more advanced features.
phpMyChat – a PHP/mySQL chat combination with a number of features.
Which script you choose is entirely up to you. As always, if the available script are inappropriate, there are many free and chargeable scripts available on the Internet.
