Any one of our support staff can reset your badges. Just email email@example.com or use the feedback form.
Right now, we can only reset all of your badges simultaneously.
Each LearnToMod account is designed to track only the account owner's progress/points score, but if you're finished with your account (maybe you've unlocked all the badges?) then you may consider passing it over to a friend or sibling, after the badges have been reset.
