Internet Relay Chat (IRC) is a form of real-time Internet chat or synchronous conferencing. It is mainly designed for group (many-to-many) communication in discussion forums called channels, but also allows one-to-one communication via private message and data transfers via Direct Client-to-Client.
First off you will need a client. I'll be using X-Chat for this guide since it's pretty damn easy to setup. You can get it here. Other clients include mIRC (with nnscript available) and ChatZilla (a firefox addon which looks ugly).
Now download and install X-Chat (not even 1 MB big) and launch.
You'll get this screen:
Nick name: The name that will show up in the userlist of the channel.
Second choice: If your nick name is already taken then X-Chat will try to use this one.
Third choice: If your second choice is already taken, X-Chat will use this one.
User name: The name that will show up as your ident. You prolly don't know what this means so fill in your nickname.
Real name: The name that will show up when someone whoises you. If you want to stay anonymous, fill in your nickname.
Networks: Our chat channel is located on the network "Quakenet", so scroll until you find it and select it.
Now press connect.
* Perl interface loaded

* Welcome to the QuakeNet IRC Network, Mithran
Congrats! You're connected to the Quakenet network.
Now X-Chat will pop-up this screen:
Select "Join this channel:" and fill in #semperdius. Press Ok.
If all went well you should have joined the chat channel and ready to chat!
