I have been aware about Discord for some time now , but I never used it because both Pharo and Unreal channels are on Slack. From my small experience with it, it seemed much more superior to Slack with added bonus that is completely free (open source ) and with no restrictions unlike Slack.

But something happened suddenly yesterday, I opened Unreal in Slack and it was gone with a notification that they moved to Discord. So I grabbed this opportunity to create a Pharo server you can join here

Discord works as web apps but also you can download as an app for Windows, Macos , iOS and Android.

I will be around in Discord because I generally browser Unreal channels. The nice thing about Discord also is that it offers both audio and video chat for free which can work great for Pharo sprints. Anyway there is no harm on testing it.
