Hi Andy,
There are lots of ways to share iRp charts and playlists.
You can use email, dropbox and other file storage/sharing services or start a *single* sandbox thread titled:
Andyspianotips charts
Then share the url of the thread (link) with your students.
Remember, from time to time admin may delete sandbox posts.
Use personal email, Dropbox, Drive, cloud, etc. to archive your iRp files and backup(s).
Thanks
)BOB
