I think that here the system message "Log of all changes to instructors."
lacks the link to [[Special:Instructors]]
I'm thinking so by analogy with the other neighbouring system messages
Log of all changes to [[Special:Institutions|institutions]].
Log of all changes to [[Special:Courses|courses]].
Log of all changes to instructors.
Log of all changes to Education Program [[Special:OnlineVolunteers|Online volunteers]].
Log of all changes to Education Program [[Special:CampusVolunteers|Campus volunteers]].
Log of all changes to [[Special:Students|students]].
@Spiritia: This issue has been assigned to you a while ago. Could you please share a status update? Are you still working (or still plan to work) on this issue? Is there anything that others could help with? If you do not plan to work on this issue anymore, please remove yourself as assignee (via Add Action... → Assign / Claim in the dropdown menu) so others could work on it. Thanks a lot!
I am boldly declining this task as there have been no updates by @Spiritia for four years, so I assume it's been abandoned.
