“When you join Straylight.cafe, it isn't connected to any external relays on purpose, so you must edit your profile and customize it for how you want your npub to appear on this site. Whatever you post on Straylight stays there and doesn't go out to the rest of nostr unless you do so manually. It's like an open telegram group -- public, but not broadcasted by default.”

Do any clients allow for using relays like this? nostr:npub1pu3vqm4vzqpxsnhuc684dp2qaq6z69sf65yte4p39spcucv5lzmqswtfch is the only one I can think of
