Hey! Sorry for any confusion. The main nostr.wine relay is just a one time payment, not a subscription so you are all set.
The relays are separate as they serve distinct purposes. Though we could merge them in some ways, we prefer to let users decide which of them they want to use even if that adds a bit of confusion. I know it’s still all a bit unrefined so apologies for that. We are still focused on functionality over polish at this point. Let me know if you have other questions!
