How do I change the Pobble admin?

You must be a Pobble admin yourself to do this.

Click 'My Account', and 'School settings' and this will take you to your Teachers page.

If your colleague is on the list, click 'assign as admin'

If your colleague is not on the list, add them by typing their email addresses in the box at the top of the team list. They will be sent an email to register. You can then assign them as admin via the steps above.
