I've received a fair amount of questions regarding IRC so I decided to write up a little tutorial on how to get into the Tremulous IRC channel. You can read more about what IRC is over at IrcHelp (http://www.irchelp.org/)
Quick Version for people who know what they are doing:
The channel is #tremulous on the freenode network (chat.freenode.net:6667) irc://chat.freenode.net/tremulous
Long Version + Tutorial
First we have to get an IRC client installed, personally (http://tremulous.net/IRC/irssi.png) I use irssi (http://irssi.org/) but most people prefer a gui client so for this tutorial I will use Xchat (http://www.xchat.org/)
Installation:
Linux - Most distributions have many irc clients in their repositories and installation is the same as any other package - some examples below:
Debian (Ubuntu): apt-get install xchat
Centos (Redhat): yum install xchat
Arch:pacman -S xchat
Apple Mac OS X - While there is a port of Xchat to Aqua, currently I recommend you use colloquy (http://colloquy.info/) instead. Installation and setup instructions are near the bottom of this post, after the linux/windows instructions. Thanks much to Das-Iro for the tutorial.
Windows - Download the unofficial build (don't worry, it's just as good!) from Silverex (http://www.silverex.org/download/xchat-2.8.6-1.exe) Save the installer to your desktop, or run it directly. Run the file and accept all the defaults (click next->next->next etc. I'm sure you are used to this :-) )
Since I am currently booted into windows, the rest of this tutorial will show me doing the setup on Xchat in windows, but the principals and settings apply to all Operating systems and clients. The Mac How to is below this.
Windows/Linux Initial Setup and Configuration
When you first launch Xchat, the settings windows will pop up asking you some basic settings:

As you can see it is asking you for some basic settings.
Nick Name - We would appreciate it if you choose the same name as your Forum name
Second Choice - In case First is taken
Third Choice - ditto
User Name - Set it to the same as your Nick Name generally
Real Name - You can optionally set this to your real-life name if you would like interested people to know it, else just set it to something random.
Now scroll down the list until you get to Freenode and click the Edit key
(http://tremulous.net/IRC/click_edit.png)
and this window should pop up:

I've put in some recommended settings for you here you should use. You only need to put in the Nickserv password if you have registered with freenode (http://freenode.net/faq.shtml#nicksetup) which I HIGHLY HIGHLY recommend you do if you aim to spend any decent amount of time online with us :-) .
Click close on that window, and you are all done with the setup!
Click connect and xchat will launch and automatically put you into #tremulous to chat with us:

Mac OS X Initial Setup and Configuration
Traditionally, chat clients on the Mac have been anything but glamorous. Colloquy is an advanced IRC, SILC & ICB client which aims to fill this void. By adhering to Mac OS X interface conventions, Colloquy has the look and feel of a quality Mac application.
Here is the latest Colloquy version (http://colloquy.info/downloads/colloquy-latest.zip)
Unzip the file by double clicking, if your Browser did not do that for you.
Place Colloquy (http://tremulous.net/IRC/colloquy.png) to your other Applications.
When you start Colloquy the fist time you get 2 Windows
(http://tremulous.net/IRC/colloquy_start_window_1.png) and (http://tremulous.net/IRC/colloquy_start_window_2.png)
We are going to use the "New Connection" Window.
Open the details, in the lower left corner.
Change "Nickname" to your nickname.
Set "Chat Server" to irc.freenode.net .
Select the "Remember this connection" if you want to do that.
Change "Username" to your nickname.
Real Name: If you want to let others know your Real-Name enter it here, or just sth. random.
And add a new Room #tremulous using the + in the lower left corner.
(http://tremulous.net/IRC/colloquy_new_connection.png)
Press "Connect", so you Connect to the network and join the channel automatically.
The "Connections" window shows the new connection now.
If you want to auto connect to this network when you start Colloquy:
Switch to the "Connections" Window, select the network and Click the "Info" button. Switch to the tab "Automatic" and select "Connect on launch".

If you do not have a "Connections" window go to the Window menu and reopen it or press ⌘ +1.
Lazy person version or 'Quick connect with no fuss'
