Padlet is a tool for displaying interactive notifications, in the form of text and multimedia. It looks like a bulletin board to which people with a link can add their contributions.

The padlet is available at the eponymous address: https://padlet.com

To create your own Padlet, you need to register on a page that is free. After registration you can create and share three Padlets in the free version.
What makes this tool even more interesting is the fact that it can be built into any other page and thus used anywhere. Students and visitors don't have to be registered to post messages.
