Thanks for responding, Derek.

Downloaded but it's beyond me technically. Archive utility icon flashes. Unzipped folder. 24 items.

Any simple YT tutorials you're aware of?

How the heck did I convert this? I have the npub saved in the same place as my hex string in the belief that it was my private key! 😏 🙄
