Can I remove the "summary" from the "Text (formatted, long, with summary)" widget? When creating a new content type, by default it has the Body field, which has a Field type of Text (formatted, long, with summary).  For this content type, I don't want authenticated users to see the summary.

What's the proper way to hide the "edit summary" part for non-admin users?  Or, am I better off deleting the default Body field and creating a new custom field?
Well, that was easy.  On admin/structure/types/manage/page/fields/mycontenttype, you just have to uncheck the box for "Summary input."
