I was able to do our first submission to the leaderboard following all the resources you shared but now the submission is under my username and not under my team name.
How can I change the name in the learderboard? Should I create a gitlab user with the team name?
Please visit the contest page and click “Create Team” button. Once you have created a team and added your team members, your (and any team members) existing solutions will automatically be shown under team’s name.
