Ok, I think the NWC I added to my profile before is there so I can Zap other people and I needed to add either LUD-06 or LUD-16 (or both) to my profile. LUD-06 is the LNURL itself und LUD-16 seems to be the same in email form. I now added LUD-16 to my profile which means I should be able to receive Zaps. Correct me if I am wrong, still learning (always learning).
