If you are an Ubuntu user or have another version of Linux, then you are probably a user of x-chat, or irssi.
The Ubuntu and Linux community offer extensive support for most if not all Linux distro's.
This support is run through what are called "IRC" channels.
IRC stands for Internet Relay Chat.
X-chat is my first choice for talking with the people at Ubuntu's IRC chat room.
I also suggest installing irssi, just in case something happens to your distro and you need help, or if you are a fan of the console, or don't use X.
Ubuntu's IRC channel can be reached at irc.freenode.org, the channel being #ubuntu.
If you are interested in this program, which is available for Linux and Windows, you can download it at:
http://xchat.org/
If you use Linux, including Ubuntu, you can install it by either using "sudo apt-get install xchat", or by using the synaptic package manager found in the system menu, then administration.
(Atleast for Ubuntu you can find it there.)
