When I go to nostr.wine, it tells me it is 18,888 sats to join. Is that forever, a year, a month, or something else. If that is forever, it is a no brainer. If it is a year, it is almost as certain. If it is something shorter, I'll have to decide what I want to do. I'll run out of sats in my alby wallet pretty fast. I can't find details on what I'm paying for.
