Thanks to Carabache and some of the Rockstars who got me onto this one. This is a great collaborative site that allows you to post stuff onto a wall that other can then access and post stuff as well. All they have to do is go the wall and add stuff. No sign in is required so teachers can get into it easily and go. You can create an account that will help to curate things but if you simply want to get something up then you can easily start and get it going.
Seems like a great tool for collaboration for anyone that is looking to share ideas and resources. The board can be exported as a document and the link can be embedded or it also creates a QR code for you to use as well. Pretty interesting and would love to see some and get some feedback on how it works.
