I know, it's a post you did on the internal relay on basspistol. I added support for authentication when browsing a public relay feed, though when posting, it needs some more work if the user should have option to post to only a specific relay. Nostria will always publish to all the user's relays.

I'm not even sure how users are expecting private relays to function, should the event be sent to participants in the thread, or only to the private relay? If only to private relay, and that relay is not part of your account relays, you won't get notified if anyone replies.

But you might not also want the events to spread everywhere, since it's "private" community relay. So how would you want it to work?
