We'll keep this quick! The purpose of this feature, found on the "manage" tab of your classroom under the "Teachers" section, is so you can quickly transfer ownership of one of your classrooms to another teacher within your Shmoop license.
Here is how to do it. Click into the classroom in question and navigate to the "manage" tab
Once you have selected the "manage" tab scroll down to the "teachers" section and click "Change owner". You can now enter the teacher's email address you would like to be the new owner of the classroom and click "Yes, Change Owner". You're all set!
Please note this can only be reverted back by the new owner of the classroom. If you have any questions or hit any snags please reach out to support@shmoop.com.
