Discord is a platform originally aimed at gamers. It combines lots of features of Skype, Slack, Microsoft Teams with no cost. You have access to a web app, a desktop app and mobile apps so can access a community from any device.
It combines the features of a chat lobby, #channels, a message board and a Voice over IP chat system. Once you’ve created a server via the browser or via the app you are ready to invite your community to the platform via a weblink.
