Hi Kwesi,
I uploaded the common material I got (mostly from Johannes/Walter 2012-14), and some I created, in "shared files". (Some are too big to normally upload, requires a special procedure...)
We are searching Google Drive again if there is more to find, and upload here. Need also to work out categories so everything is easy to find, when there will be time...

All MTs should be asked for material to share, so white-label quality versions can be put together - another group project.

Best, Kora
