I replied on other thread request for joining. I’d also suggest using something other than discord(for many reasons), XMPP worked fine for other groups I’m part of, matrix had some issues but still kinda works. IRC is good but is most difficulty technicaly.
XMPP is pretty mature, groupchat works and clients are available for all major platforms. Conversations(andorid), Gajim/Dino(Linux, Windows), Monal(iOS) etc.
i’d argue its better for software to max foss license like AGPL, not bsd that can be taken out by companies
