It was easy to use for the teachers and easy to install

Mango is very user-friendly for anyone who doesn't have a design background.

Mango is a great program if you don't need to do much customization to signs. Their templates are functional and effective; I would imagine if I worked in a restaurant or retail space they would be the perfect program. Its very much a drag-and-drop interface, with pre-made templates that you can easily load your own photos and text into. Scheduling and management of multiple signs and slideshows is easy.
