My kid has found out that he can farm items in games, but he doesn’t want to throw his life away in front of the screen so he found a solution.

Thank you for wanting to help! There is very little actual work involved. It's about 80 card descriptions that need to be controlled and understood from a language and security perspective, so that the meaning is correctly conveyed from English to Dutch. Sorry for my previous misspelling.

We have reached 99 stars. Are you going to give us our star 100? OWASP Cornucopia’s popularity is increasing at an alarming rate. Gamification in security requirements analysis and threat modeling is not a blib, it is here to stay.
