Interesting, didn’t know that it exists. How should I? 
This is exactly what I mean. This is a great feature and people love chats. Me too. Why is it hidden for the majority of users? Thousands of Discord servers are open (at least in terms of what Discord considers “open” in their walled garden) for anyone.
Hey, thanks for chiming in! Great to see that you’re working on all these things 
But this is more a matter of the UI in the front end. Just want to drop a quick message? Fine, here’s an input field and a send button. Want to send something bigger, more formal? Also fine, click on this “rich message” button and leverage the full power of Discourse. But the backend for both could be exactly the same. In the end it’s just some text with markup. There should be also only one central place to see all private communication. Anyway, that’s something for a dedicated discussion
