Use this option to restrict lockbox pages to individual members only. If you select
'Portal Only' this tab is hidden. Use the input box to search for members, when you find the desired member, click to
add member to list. Note that the member isn't actually added until the 'Add Page' or 'Update Page' button is clicked. Likewise click the delete
button to remove a member and then the 'Add Page' or 'Update Page' button to perform action.
Members are shown beneath the input box. See below example.
