Age Gate / Flag something (parent signs off?)

There needs to be some sort of icon or something telling everyone who is a minor on this site . Maybe some kind of restriction I don't know. I mean on the one hand it's good that kids make things and get creative but on the other…I just had two projects cancelled because the creator's mom decided they couldn't use the site anymore. So like…there needs to be some kind of warning before anyone joins a project. Actually maybe you should require the parent to sign off on EVERY project a minor gets involved in or creates or auditions for before allowing it.
