Connecting to Twitch IRC can be quite the task for those not knowledgeable with IRC clients. However, the process isn't too difficult. For this post, we're going to set up KVIRC using the steps below:
Adding a Network
Navigate to Settings > Configure Servers...
Select the New Network icon in the top right and create a new network. I’ve named mine simply “Twitch”.
Next select New Server and enter irc.twitch.tv in the Server field.
Check Connect to this server at startup to join the server automatically whenever launching KVIRC.
Now simply click Connect Now.
Standard IRC context applies here as above. To join a channel, type /join #channelname in the dialogue box.
KVIRC can be configured to join channels automatically, as well. To do this, select the Join Channels tab in your Server Details page. Add channels by typing the channel name in the dialogue box and clicking Add.
