I'm sure I must be doing something stupid, or just not understanding things...
I've got WPM 2.6 installed and have defined a bunch of custom fields. Some of these are for admin use only, so to stop individual users seeing/amending them, I unticked the 'displayed' box, so that they don't show up on registration forms or anywhere else a user can look. All OK so far.
They now don't seem to show up anywhere - so not even the admin can see them. Since I can't see the point of being able to define a field that absolutely no-one can see at all, I figure I must be doing something wrong...but what?
btw - to whoever wrote this: I've looked at several ways to manage a user-driven WP site, and this comes easily closest so far - thanks!
