ARSC Really Simple Chat is a Web chat system that uses PHP and MySQL. It works with every browser in existence, even text-based ones, and it uses the server push technique or, if possible, its own socket server. It is very simple to install and use ARSC. It includes some important features, such as operators, kick-ing, whispering, and more. Multiple rooms and different languages are available. To run ARSC on your site, you need a Web server that understands PHP, and can connect to a MySQL database.
