 \item Custom Helpdesk Roles
 
-Users assigned a Domain Helpdesk role may also be assigned rights to 
-select specified custom ad hoc course roles from the roles screen.
-
-Each custom ad hoc course role is created by a Domain Coordinator via
-the Support Settings screen.  A name (which will be permanent) is 
-assigned to the role, as are the privileges in a course available with 
-that role. The privileges can be modified at any time.
-
-If it is planned to use tiered helpdesk support for a LON-CAPA domain,
-the different ad hoc roles might be named: levelone, leveltwo etc.,
-with greater privileges assigned to the higher level support role(s).
-
-To permit a user with an unexpired ``Domain Helpdesk'' role use of
-an ad hoc custom course role, a Domain Coordinator must assign
-rights to the particular user to use that role.
-
-Once custom ad hoc roles exist in a domain, an ``Ad Hoc Course Roles
-Selectable via Helpdesk Role'' block, listing the custom roles, will be
-included in the standard ``Modify existing user'' page used by a
-Domain Coordinator to modify authentication, user information,
-and roles for a particular user.
-
-On his/her own roles page a user assigned a Domain Helpdesk role will see 
-one or more role names in the ``Ad hoc course/community roles in domain''
-line beneath the Select button for the helpdesk role itself.
-For each role name a Select Course/Community link will be included.
-Clicking the link will display a pop-up window used to search for (and
-select) the course/community in which the corresponding ad hoc custom
-role will be used.
-
-When a user has selected an ad hoc custom course role, the role name
-will be displayed at the top left of each LON-CAPA page, after the word 
-``Helpdesk''.
+Users assigned a Domain Helpdesk or Domain Helpdesk Assistant role 
+in a domain may also be assigned rights to temporarily acquire custom 
+ad hoc course roles.
+
+Each ad hoc role is created by a Domain Coordinator via the Support 
+Settings section.  An internal name (which will be permanent) is 
+assigned to the role, but all other role settings can are modifiable.
+These include the role name shown to users, the choice of which 
+Domain Helpdesk users may acquire the role, and the privileges conferred
+by the role.
+
+On his/her own roles page a user assigned a Domain Helpdesk (or Domain
+Helpdesk Assistant) role will see a 'Select Course/Community' link
+beneath the Select button for the helpdesk role itself. The link launches
+a pop-up window in which the course/community where the ad hoc role is
+needed is searched for and selected.  Once a course has been selected, 
+a modal window for role selection will be displayed if the user 
+has rights to use more than one ad hoc role.
+
+Course owners can override ad hoc role settings within their courses
+via People $>$ Users $>$ Helpdesk Access, including defining which 
+helpdesk personnel may use each ad hoc role, and overriding the 
+selection of course-level privileges defined in the domain configuration.
