To see the new logo, you need to exit out of the program/browser and log back in. Keep in mind you can replace the logo or the text - but not both. Best option is to use a logo that has the school name as part of the logo

How do you change the purple box that says "Our School"? I have hit edit and entered another .gif image and typed in new text, but it keeps coming up as the same purple box, same picture of a school, same "our school".
