This was something formed in 2009, and that a number of players used for a long time. I haven't been there since 2010 or so, and this Java applet may have some serious problems for all I know. At any rate, when redesigning our site, I didn't feel like this deserved such a place of prominence (in one sense) being on the main community section. And on the other hand, I didn't just want to ditch it AND I felt like this forum was actually a better place for it to get more visibility anyhow. So here you go!
AI War Applied IRC Channel
A Real IRC Client Is Better
You can easily connect with any real IRC client, such as HydraIRC. Getting started is easy -- simply click the following link once you have an IRC client installed: irc://irc.rtsnet.org/aiwar.
If you have not yet set up an Identity in HydroIRC, you'll want to enter a nickname and such for yourself, and then it will connect you right through to the AI War IRC Channel. That's it!
