Hi there folks, long time enthusiast and player of sub sims. just got into dangerous waters and I'm glad to see that there is an apparent active community playing Multiplayer mission.
I would love to join but I really don't like the data abuse track record of Discord's developer and so I choose not to use it. Is there any way you would be willing to facilitate those who don't want to use discord?
If not, no problem and I understand.
Incidentally, there is an free and importantly open source group chat called Riot running on the matrix network. It can also be self hosted and isolated if one so chooses. Moreover it has all the features of a Discord or a Slack with an IRC style public channel browser. If you are concerned at all about data privacy and decentralised solutions, i think it's worth your time.

Have fun
