Connecting to Twitch IRC can be quite the task for those not knowledgeable with IRC client, check out how you can set yourself up connecting to Twitch chats using KVIRC.
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 “Twitch”.
Next Select New Server and enter irc.twitch.tv in the Server field.
Next click Advanced and enter your Twitch user name in the Nickname field and your OAUTH token in the Password field and click OK
Note - You may check Connect to this server at startup to join the server automatically when you start KVIRC.
Now simply click Connect Now.
Standard IRC context applies here as above. To join a channel simply 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 (Don’t forget the #hashtag).
