A Signal group to discuss sports, meditation, food, sleep, and all sorts of other healthy things.
We focus on being environmentally acceptable, i.e. no keto carnivore nonsense ;)
To join, please make a nice profile pic and name, doesn’t need to be something personal.
Matrix has better moderation features, if that is what you mean.
But personally I know no Matrix client that is reasonably responsive, all slow goo that is a pain to use. Signal is not optimal at all, but Matrix is kinda worse.
I think XMPP or SimpleX (very different approaches) are better here. XMPP better suited for public groups where you need spam protection
