Just a reminder to everyone (me included) that Categories are pluralized. For example Category:Characters is correct, Category:Character is incorrect. Currently I'm going through Category:Location and changing the entries to Category:Locations. Apparently, the only mass change you can make to a category without using a bot is capitalization so you might say it's slow going. So if you happen to see another non-plural example in some other category, please take a moment and fix it.
