You can load a copy of whiteboards directly to your class room's whiteboard which have been shared by a Premium user from their Library.
Loading shared whiteboards to a class room's whiteboard does not require a Premium license.
To load a shared whiteboard, click on the Library button, and select Load shared whiteboard.
Then, paste or insert the whiteboard code, and click on Load shared whiteboard.
When loading a shared whiteboard, you load a copy which is made at the time of loading. This means that changes you make to the whiteboard are not shared to the original whiteboard, or vice versa.
