I used Discord for a while and I'm confident I can describe most communities on there.
There's an #\offtopic or #\general where most of the activity takes place.
There's a #\memes with moderate activity.
Maybe #\animals for cute animal photos.
#\rules and #\announcements of course.
If the server owner is a creator they have an update channel for their own works.
#\welcome to greet everyone the millisecond they joined which is just GREAT for people like me who want to check the vibe first.
Maybe there's a forum channel, and it's basically dead.
