Could you please shed some more light on this community? Maybe a link that describes it properly - I can google but could stumble upon maybe an unfactual website without knowing it.
A community that encourages niceness is something I haven't really heard of before yet sounds super interesting - that's not to say that a community has to explicitly say they're nice to be nice. I know I've had my fair share of going out of my comfort zone meeting others and not knowing whether they are "that" person or not. Although maybe it's good for me to come to terms with knowing that not everyone is friendly and that that's okay.
