User blog:SpamCrackers/How to edit info boxes. . .

There are a couple of things I think should be added to some of the info boxes. One example would be a "Religion" category for the few character to whom it applies. Is there any way to do that?

Also if I wanted to add information to those boxes is there a way for me to do that without replacing the existing information? I've been afraid of accidentally doing that. Just a little confused because they're set up differently than the rest of the page when it comes to edit.
