If you complete the workout at a CrossFit affiliate you will need to have your score validated in order to have it appear on the Leaderboard. You need to make sure your affiliate has an Affiliate Manager. The Affiliate Manager is the person responsible for validating the scores AFTER they have been submitted.
The Affiliate Manager from the affiliate where you completed the workout is the only person who can validate your score. They will need to log into their account and validate the scores before the validation deadline. The validation deadline is always Wednesday at 5:00 p.m. PT.
If you are submitting a video for your performance the score and video will appear on the Leaderboard as soon as it is submitted. You do not need to worry about having a video submission validated.
