Could you give us some insight into how much bandwidth up/down your instance is using? Thanks for posting your server specs. I'm tempted to self host an instance when I finally get a gigabit connection in the next few months.
So our discord regularly has friends and family in the age range from 17-59 currently who all game and socialise together. I don't think there is a limit.
Keep taking a look at myanonymouse. They open up registrations regularly. This place will have what you're looking for along with a great community.
My dude, could you pass it on please?
