Hi @Alex939,
This is indeed what it says:
Welcome to the Community, Cor
Join the conversation and connect with other hosts who are creating a world where anyone can belong.

So, it is indeed referring to: "other hosts", but the counter states: "members".
When there is a post by someone, that is not a host. Then you cannot send this person a private message.
I've been in touch with Non-Hosts on the Community before.
It is even been heard of that salesmen send in inquiries for a booking, in an attempt to sell something 😞
Although Airbnb does not release any figures. I would assume that there are over 2 million hosts on Airbnb.
So the number of Superhosts among all hosts is about 20%.
Furthermore I would assume that about 50% of all hosts and accommodations on Airbnb are actually NOT active.
