Loved seeing you there. Too bad we never got to meet in person. You are a Nostr superstar. 

I’m developing onboard tools for people like you to share custom invite QR codes. Bring people to YOUR corner of Nostr with a single link. As a Nostr influencer, I am building for you. LMK if you have any questions or wishes.
