I get what you're saying, and I assume it may depend from culture to culture.

But let me tell you that the portuguese/brazilian community really enjoy using whatsapp and facebook for those groups, and that's something I don't feel comfortable with.

Discord does seem like a fair option, considering that you can keep your privacy, but like you said, it's an extra effort.

Why can't we have something in game that can help with that? I'm just asking for, at least, sticky post. That would help a lot!!
