@maroon You need to run this on connect:
CAP REQ :twitch.tv/membership
CAP REQ :twitch.tv/tags
CAP REQ :twitch.tv/commands
After about 60 seconds, the user list will load.
You also need to remember to connect to the correct channel, the format of the channelname needs to be all in lower case. If there is a single capital letter, it will not connect.
