What IRC clients are available?

I believe the question says it all.

Please and thank you.

• XChat

  XChat is a graphical IRC Client with a GTK+ GUI. It has a look and feel similar to AmIRC for the Amiga. Special features include the mIRC extension DCC RESUME and mIRC color, multiple server/channel windows, dialog windows, and a plugin API.

  It does pretty much everything you could want an IRC client to do.

• IRSSI is the way to go: http://www.irssi.org/

  It was even in the TV show 'Numbers'; check out the video on the Irssi homepage. (P.S. That was supposed to be funny)

• Empathy!

  Installed by default in Ubuntu. It really serves as a very easy to use IRC client. Don't expect very advanced features though ;)

  DrKenobi : I think Empathy is OK. You can't expect many features on IRC.

• Quassel is another IRC client for Ubuntu. It uses QT.

  csgeek : if you don't want to use irssi Quassel is great. I can run headless, and do a server/client setup where you just "connect" to your irc session that was running in your remote machine, or headless

• I always liked pidgins irc but pidgin is another empathy. If you want a totally separate client for irc, I would recommend XChat. Both are available in the Ubuntu Software Center.

• XChat-Gnome

  XChat-Gnome is very similar to XChat however it aims to have a more friendlier user interface and integrate better with your desktop. I find for starting out on IRC its much easier to get the hang off

  sudo apt-get install xchat-gnome xchat-gnome-indicator

• I use Opera browser's built-in chat client. During Ubuntu Openweeks I just have to click the link to the classroom that is present on the openweek wiki page and the chat window opens in another tab.

• Smuxi is a nice GNOME IRC client, which features indicator support like xchat-gnome, and can be run in a client/server arrangement where the server is always connected to IRC, much like irssi+screen.

• If you're looking for something dead simple, I'm becoming a fan of LostIRC.

• I use Firefox browser or Empathy

  fluteflute : Firefox is usually seen as a web browser rather than an IRC client...?
