Hi, I work for National Geographic and it's come to our attention that one of our episodes aired with an incorrect credit. We're working to change this on our air masters but we also need to change it here. How do we go about that?
I guess basically the original ”wrong” credits should stay on the site with ”(credit only)” attribute, and the new ”correct” credits should be added with ”(uncredited)” attribute. Then perhaps note to the Alternate versions section. (Not sure what type of corrections will be made to the episode, though.)
Not the ideal way, but since there are some guidelines on IMDb...
