TL;DR
FIRST: (Optional) Install Cacert root certificate to avoid getting SSL warnings: http://www.cacert.org/index.php?id=3 (Note the very first link is aimed at Windows, the rest aren’t. You can completely ignore the first link (The MSI) on ALL operating systems).
SECOND: Access https://chat.wargeeks.org
THIRD: Register with a KNOWN username (preferrably the same as what you use on the site)
FOURTH: Access the War Geeks channel.
FIFTH: (Optional) Use an XMPP client to access the chat outside of the web, view your profile on let’s chat to get the settings.
I’ve set up a shoutbox alternative called Let’s Chat. It’s an entirely new system that you can run in a new tab or window. Unfortunately you’ll have to register to use it. It’s run by me, so you’re not handing off your details somewhere dodgy (well, dodgier than I am anyway). Although it asks for email during registration, there is currently no way for the system to send emails (that I’m aware of), so I have no idea how password retrieval will work just yet, if at all.
Once you’ve created an account on the system, you will be able to use certain XMPP/Jabber clients to connect to it without using the website if you don’t want to. Click your username at the top left, and click on the XMPP/Jabber link to get your connection details.
While most XMPP/Jabber clients should work, these ones are known to work:
https://adium.im/ (OSX)
https://www.pidgin.im/ (Win, Linux, OSX)
http://profanity.im/ (Console based, Win, Linux, OSX)
http://psi-im.org/ (Win, OSX)

For IOS users, if you find anything that works, post here.
The new chat system is using SSL(TLS) (for both web and XMPP), to avoid SSL warnings, please install the root certificate from CACert - I find the Windows MSI installer a bit dodgy, so rather install the class 1 PKI certificate. You can install it in your Trusted Root certificate store.
The chat system can be found here:
https://chat.wargeeks.org
I will leave the current shoutbox running for a few days before I replace it with a link to the new system.
When you register on the chat system, please register with the same name that you use on the forums. If you use something different, it’s going to be confusing.
