IRC (or Internet Relay Chat) is a form of real-time Internet chat or synchronous conferencing. It is mainly designed for group communication in discussion forums called channels, but also allows one-to-one communication via private message, as well as chat and data transfers via Direct Client-to-Client.
If you use firefox, you can use chatzilla, or if you don't you can always download MIRC.
I could probably help you set a channel up too.
Channel is up if you want to try it.
