Bocazas is an applet program that runs on any webpage and operating system. If installed on your web page the visitors will be able to access any chat network, have public and private conversations simultaneously, direct connect to other users and send files.
Eventhough it is a powerful program that accepts all IRC commands, it has an easy interface and supports several languages (English, Spanish, Italian, Deutsch, Catalan, Galego...) therefore it is quite intuitive.
