@iandaemon You're true, the forum cannot be replaced. This is the best information source.
Discord Channel is more to speak with peaple, make friends, play together.

Why the language is an issue? Most peaple speak English all over the world. (i'am French for exemple)

Does Discord has an application that can be run on a Raspberry PI ? Their clients include mac/windows/linux (x86) or android, but I don't see anything for a system with ARM CPU.

As far as I know, RetroArch on PC/Mac/Linux has the possibility to interact with Discord, but in the end it needs to be properly integrated into RetroPie.

What are you thinking when you say 'integrating' ?
If it's already included in RetroArch, the you can configure it and you're good to go.

Wow, two years going forward, and I think I've really helped build a community here. Man, this takes me back.

@Swagman89 yes IRC freenode #retropie

We already have an IRC chat, I think that is good enough
