Yeah, you can think of it that way. I was mostly trying to make it work since I couldn’t find a NIP specifically for subscriptions.
And yeah, I can add people to the list manually, just as I would be able to on listr.lol
Re: clients checking for an opt-in event — that’s where my client isn’t interoperable since I’m using Supabase. But I would be glad to refactor once I see a NIP for it. Guess I could just make something up right.
