I am a administrator of the Cataclysm-DDA Discord server, and I would like to appeal to those on the forums to join us!
Discord is an chat service for gamers, along the lines of Skype and TeamSpeak. On Discord, we are able to host more informal conversation about the game. Additionally, the developers can reach out to the community for their ideas easier. We also have a friendly community, and a effective moderation team, so you can make yourself at home. We have already accumulated 800+ Cataclysm fans on our Discord server, and we hope that you can help us grow.
Here is the invite link: https://discord.gg/DPxUcX7. Discord works in the browser as well as having mobile and desktop versions, so you can access the server anywhere!
