This is the NITW chat for the Wiki which is used very rarely.
For the Discord chat, please take a look at the widget on the right side of the page. Here is the list of those who have wronged the chat and must be purged.
It is an "All-in-one voice and text chat for gamers that’s free, secure, and works on both your desktop and phone".
Basically, it is like TS3 or Skype, except it has multiple voice and chat channels, you can be in various servers at the same time and it accepts Twitch emotes in real time, people talking in them and how many players are online.
When doing so, the action taken must always be justified and explainable, should an administrator investigate the situation.
