We use Discord as a multi-channel text chat (like a dedicated Whatsapp) during the Festival (and before). It will also host our Festival Radio! You can access it through a web page or (better) by installing the app on your phone/PC. To join our discord, pop over to https://discord.gg/RKSjwdg
You’ll find channels for general chatter and other Festival organisation, as well as ones for specific games. It’s a great way to keep up to date both before and during the festival.
