you would be surprised by how many english speakers take my book to learn spanish. Once, someone approached at the meetup and said that he's learning spanish with Lunaticoin's podcast and my book

~That's the moment when I realized I was God~

promote them to those english speakers that want to learn spanish :)

The books are in Spanish, most of the users on SN and Nostr are English speakers. 
But, I can try it out.

Thanks

Could try a v4v thing on nostr or even chapter by chapter on SN.
