Is there anything like a SimpleX group chat to join for us to talk, or should one be started?
SimpleX is not suitable for larger group chats.
XMPP has a few quite popular privacy related public channels: https://search.jabber.network/search?q=privacy
(For those unaware: xmpp participant counts are actively connected users, not like Matrix or Discord that counts who ever joined the room years ago and never came back).
I joined Privacy and Security
Define larger groups because I know for a fact that it can do chats of up to at least 1,000 people because I’m in two group chats that have that many on SimpleX.
There is! But it’s only in signal

Why is this not linked in the sidebar?
Because Signal does not fully respect your privacy.
If by that you mean the Unix time, then yeah, but There has been documents showing that Signal doesn’t store sensitive plaintext data.
IMO because it’s a Signal group and you can’t separate user profiles and have to register with a phone number (yeah I know I know you have a username now). Some people including me won’t join therefore
