Computing an editors list from the access control list
The status section of a Business Card Request form has a controlled-access section whose formula allows only administrators (an access role in the ACL) to change the status of a request. The formula for the computed field is:

"[Business Card Administrators]"

Allowing the author to name section editors
An editable section of a Status Report form has a controlled-access section whose default value formula always allows the author to edit the status report. Users who have access to the document but are not the author can read the section but cannot edit it.

"@Author"

The author can choose Section - Define Editors to name additional editors for a particular status report.
