EW got back to me with details of the two new profs (still missing a bio, but enough), so I created the new prof pages and checked they worked. The 301 course was still not showing up on the prof's page, so I checked around, and eventually found that in the /includes/course_listing/courses_taught.php page, the block of code handling this prof's courses had been tagged with the wrong prof id. Now fixed, and all seems to be working, so I've made the names back into links on the People index.php page and the secondaryNavbar.php include.
