What happens if my fountain.fm account is linked to #Nostr ? I think fountain is working on full Nostr integration, too? As fountain is part of zbd I'll probably run into similar issues, I suppose? 

 Ok, all clear! So, fountain is only asking for your npub to create a simple link to your #Nostr profile not the nsec yet...
