There wasn't really anywhere else this would fit so I'm putting it here. I set up a UKCS Discord server with permission from Unspecified.
The Discord desktop and mobile app can be downloaded from https://discordapp.com/apps
Once installed you can join the UKCS server by clocking the + sign on the left side join server and paste the address https://discord.gg/6wyAEVT
Hope this helps.
Discord is a lot nicer to use then mumble and had much better social features.
