When LEGO Ideas was known as CUUSOO, users had to be 13 years or older to create an account, but 18 years or older to submit a project. Since April 30 2014, users still have to be 13 years or older to create an account, but now all users have the chance to submit a project. If the project creator is under 18, they require parental permission for their project to be produced if it passes the review.
