+# When grade passback mode is 'homework', someone must use a set-specific link from the LMS in

+# that a user in WeBWorK sees the sets as disabled and there is a message about needing to
+# access the set from the LMS. The following option can be set to allow users to work on the set
+# anyway. There will be no grade passback until some later time when an LMS user clicks the
+# set-specific link. In some LMSs, it is possible for the instructor to activate the link.
