When uploading media the user can select a License for his works. The several types of Creative Commons licenses could be explained so the users can make informed decisions which license fits best.

The same could be applied in the „Edit Profile“ screen, where the standard license is set.

This could be accomplished by adding a link "License information" which opens explanations in a pop up for example. The most basic solution could be a link to this external page:
