No, the one you are thinking of is Laser Discord. I don't spend a "lot" of time in there, but I do read through the backlog. The one I invited you to is the SELEM discord server.
yes, I didn't create it, so I can't change it, but I'm in there quite a bit. I was invited a while ago, because it was created for having communication at SELEM (because it gets hard to find people) and past SELEM attendees are typically the people who are in it.
I'm not sure which "rough characters" you are referring to, but more recently I haven't seen anything that I would judge as unfriendly.
Bottom line: you do you, Boo, but it's there if you want to try again; I was just trying to offer an opportunity to connect.
