Turn off the teacher in the course description on front page

Where i have created a cohort to enroll accounts across many different courses, the names of the teachers in the cohort are displaying on the site front page, like this.

My customer, who is in the manager role asked me "Is it poss. to turn off the teacher name display?"

I am off the investigate, my guess is a front page option.

This was the useful forum discussion, as I was about to open the core.css file and remove some code, I saw Mary Cooch post toward the bottom of the forum

 "By the way - you don't need to change the code to hide the teachers - you can do this via Settings>Site administration>Appearance>Course contacts and uncheck Teacher."

I was about to bring a sledgehammer to the fight, when I only needed a screw driver.
