Goodmorning!
I am putting together a family friendly discord called the cub club.
The game is not made for kids but I play with my girls and we have run into other kids. My plans are to have a group where kids can chat safely with other kids in game. I would (And eventually maybe other trusted parents/adults) be a kind of built in Nanny when the group is live. We disable in game chat and turn in game voice all the way down. I can also stream so that parents can watch their kids play.
This still is not completely without risk but I think we could make it pretty safe. Would anyone be interested?
Edit to add:
This is the discord. I have a room page called friends of the cubs as a public page.
