Should Filmography/Appearance sections be listed according to production order or air-date order? I've been doing the animation studios pages by air-date, using Dan Riba's page as a base, but then noticed that some (perhaps most, I've only gone through a couple) character pages go by production order. Is there a specific order that should take priority?

Yup, we use production order for Filmography/Appearance sections. Although we don't have a written rule. ― Thailog 22:47, 4 February 2009 (UTC)
