How do I become a creator? 

To get creator rights you have to sign up for the launchpad on either enter.art or enter.audio. You can do so via these forms:

enter.art: https://share-eu1.hsforms.com/1r2OC4FBiTNeRgAm6lOs8iQevopv

enter.audio: https://share-eu1.hsforms.com/1L_Bn7qctS_yG8qE7qV1EoQevopv

Don´t forget to create a user first!
