To be able to reQuest this badge, you need to have fully taken part in a LC in the old forum (pre 2020).
Badges have already been given to the challenge winners, so do not choose a LC in which you won.
- name the Challenge eg LC 64 - Winner: Obliverum
- copy/paste the url eg LC 64 - Winner: Obliverum
- use the share icon at the bottom of one of your LC posts and copy/paste the direct link to the post
One of the moderating team will then add the badge to your profile.
