Completely annonymous chat! Somebody acts as server, and somebody acts as client, like web hosting where there is somebody with a web site and somebody who is visiting.
The server is setup by someone (using a desktop). Once server launched the wierd code at top-middle is server id. Give the server id to someone who will be the client, this is like the url of the website, they enter it client section below, this is like entering a url into a web browser. The server chooses the chat in the incoming senders from the left side.

Use of this software is your agreement to use "as is" and not to sue for anything if you have a problem.
