IRC with Adium
IRC is a great way to get help when you need it, and it’s even easier now that your favorite OS X IM client supports IRC. Here’s how to get up and running.
1) Create an account
Add a new IRC account. Enter your nickname, host server (irc.freenode.net). You probably won’t need a password.
2) Join a group chat
Make sure your new IRC account is connected, and select ‘Join Group Chat’ from the File menu. Select the IRC account from the drop-down, enter the chat room (including the ‘#’), and join.
