I'm guessing that I need to do raw CAP REQ :twitch.tv/tags. But when I do it, my bot wont get any of the chat messages from twitch. Do I need to add/do a script to capture chat or something?
What version of mIRC are you using? I'm using the latest, and requesting the following:
raw CAP REQ :twitch.tv/membership
raw CAP REQ :twitch.tv/tags
raw CAP REQ :twitch.tv/commands
Chat messages appear just fine for me.
