The term “access-control-discontinuous hyperlink” is used to describe a hyperlink which at least one user (an authorized user who could be reading its containing document) isn't authorized to follow. Discontinuous hyperlinks are automatically detected at various times, including at the end of document editing. If any are found, the operator is notified and given options to reduce the number of discontinuous hyperlinks and to reduce the number of affected users. Several alternative views of relevant information are provided, integrated with common document editing user interface elements. Sorted views enable the operator to identify and to remedy problems more efficiently and with greater confidence. Access dependency settings for selected text can be inserted with a single command. The operator can preview what various sets of users would see. Users are graphically represented by displays comprising photographic likenesses. Groups can be graphically represented by displays comprising photographic likenesses of selected members.
