So you can use any nip05 to write on your relay? It seemed that one needed YOUR nip05, bought from you, to write to your relay...
But you're saying that I could write there with my '@primal.net' identifier? Sorry for the confusion...
No, you were right the first time. They need a happytavern nip5.
But why are you doing that? The incentive to write to your relay will shrink compared to just paying a lightning invoice to get white listed.
That way the only people that are writing to it have to have their nip5 as happytavern. I want to keep my relay small.
