I know I had to find out how to do that the long way myself, haha. The main thing for me was that we had almost all Fair Use images (a few edited, very few self), but no one knew what "Fair Use" meant. So I changed the licensing drop-down to be more newbie-friendly and less confusing.

Possibly also mention of adding default text to the Summary box. I recall several wikis use that box to make sure that every image has a licensing template. This can be fairly useful if it's a template that requires that information be filled in.
