Chat Creator (www.chatcreator.com)
is a free, fast system without recording in order to create online a
private chat and to insert it through copy/paste of the code in the
pages of your own site: you will be able then to invite people to
participate. It's enough to choose a name for the chat room and
ChatCreator will create it automatically and will accommodate it on its
server. For who has difficulties to understand the mechanism of Chat
Creator, there is however on the site a section for the FAQ.
