How to show a custom field to admins only on Add New/Edit screen?

Hi folks,

Just got a quick question here: How do I show a custom field to admins only on the Add New/Edit page? I'd like to be able to get the value to be shown in public, but only allow an admin to set the value.

It's the one thing I need to be able to setup a fan fiction archive using this plugin and the Organize Series plugin (organizeseries.com). No need for post2posts or any other plugins. :wink:

Thanks,
Nathan Pinno
