I'm remixing across libraries and ran into a problem with the author bar. The original page in the mathematics library has an author bar for Oscar Levin: After remixing it in a text in the engineering library, the author bar is blank except for the words "Contributed by": I'm not seeing an option for Oscar Levin in the engineering library's author list. Is there a way to add it, or should I just put the author in a Contributors section at the bottom of the page?
