Create an option for users to add creator(s) and characters/users to submission information, with that directly linking to their user profiles.
Imagine this as a system with what you can set in the names of artists directly linking to profiles and characters that are visible on the submission stating both their name and their profile link that everyone can access.
This would be handy because we don't have to type out copyright information onto the bottom of the image, plus stating who's character they are. (Some users do this and this would be actually a very good thing for others too who don't do it.)
