Internet Relay Chat, or IRC, is essentially the chat room service of the Internet. Anyone in the world with Internet access can log on and chat or exchange files. To connect to IRC, you first need to download and install an "IRC client." Once you're logged on, you can join one of the IRC channels, or chat rooms, devoted to TI graphing calculators. You can ask (nicely) for help, discuss programming tips, or just hang out, all in real time.

For Windows, we recommend the mIRC client.

For MacOS, we recommend the Ircle client.

For Linux and other UNIX flavors, we recommend the BitchX client.

For BeOS, we recommend the Felix client.

To access these channels, join an "EFnet" IRC server. It's also a good idea to read up on IRC basics before diving in; experienced IRC users are not historically forgiving of new users who ask common questions.
