Whats the mnChatProject?

Greatings =)

If you ask now: "What the hell is the mnChatProject?" i can answer this question in just a few words.

The mnChatProject is a Project by myself on creating an ICQ-Like Java-based ChatClient and Server.

Why do i want to do this?

It's very simple :)
The normal ICQ-Network is not opensource (that means that you can't edit any files for free).
So i want to create a ICQ-Like Network programm which is opensource and which is written in a language which can be understood by everyone.

Another thing is that ICQ can't encrypt your messages which means that everyone who is listening in your network is able to read your messages.
My client and server are communicating with 64bit encrypted messages which means that you can't read the messages without decrypting them for many days.

Thats the two reasons why i want to programm this project.

On this blog i am going to poste what i have done, what do i want to do and so on ...

Here is a screen of the Client how it looks like at the moment:

So if you are intrested stay tuned =)
