If you published a loop in your school’s library by mistake, or if you want to remove a loop for some other reason, you need to find the Loops Administrator at your school. The administrator has the authority to remove loops from your school’s library. If you don’t know who is the administrator at your school, you click on the name of your school in the bar at the top. You then click the headline Students and after that Teachers. In the descriptions of the teachers you can see who has the administrative rights.
