We don't currently offer this functionality, but will be building it in down the road so stay tuned. In the meantime, we have a few ideas if you'd like to share newsletters, handouts, or any other printed information with your families.
One possible solution is to link to those documents in a child's profile or via the Notes category of our Activity feature. First, upload the document to the cloud with tools such as Google Drive, Skydrive, or DropBox. Once you've done that you can paste a link into a note.
Another common workaround, especially for newsletters, is to take a photo of your newsletter and then share it through our Activity feature as a Note and attaching the photo.
