[twitch.tv](https://www.twitch.tv) is an online streaming platform commonly used for people to watch people play computer games. It is also suitable for live streaming lectures however.
#### Moderating Twitch Chat (thanks to our TA Yoshi van den Akker for text contributions)
Twitch comes with a chat feature in which viewers can comment and ask questions to the live streamer. For [interactive lectures](Interactive Lectures) this can be a good way to receive questions from the students.
Due to the large and uncontrolled setting however, it is probably wise to ask one or more teaching assistants to be present to moderate chat in addition to enabling "slow mode". This can be done by clicking "Chat Settings" and then "Slow Mode". The interval you select determines how often students are allowed to type something in chat. We recommend selecting at least 10 seconds to prevent an overflow of comments from students.
To this end:
- Make them a moderator by executing the command `/mod <username>` in chat with `<username>` being the username of your TA (without the angular brackets).
- The TA should now have a screen similar to this 
- With the mod abilities you can enable "mod icons" in the settings menu. With this 3 buttons appear next to each chat message: ban user, give user a timeout, remove message.
- Other commands include
- BLOCK
This command will allow you to block all messages from a specific user in chat and whispers if you do not wish to see their comments.
- Usage (chat): /block USERNAME, or click on a username and then on the Block button on the user badge that appears.
- Usage (whisper): Click on the cog icon at the top of the whisper window, and then on Block USERNAME.
You’ll be asked to provide one of three reasons for blocking the user.
- UNBLOCK
This command will allow you to remove users from your block list that you previously added.
- Usage: /unblock USERNAME, or click on the Unignore button which replaces the Block button.
