So Microsoft Teams EDU is a new layer added to Sharepoint/Office365 to make the space workable. Sharepoint/Office365 is ridiculously powerful, but like all ridiculously powerful applications, they need mediation to make them open to the average user. (For regular OneNote Staff Notebooks, see here: Nudging the OneNote Staff Notebook Permissions ) When you create a new Team, you choose its type -- Classes (for, you know, classes), PLCs, Staff Members and Anyone. For PLCs and Anyone, you just get an open OneNote Notebook without any specially permissions sections. When you choose a CLASSES or STAFF MEMBERS teams, a Class or Staff Notebook (respectively) is made with a Collaboration Space (open to all), a Content Library (read by everyone, editable by the owners) and individual private spaces for each member. Now, I was asked if it's possible to nudge permissions on these Class/Staff Notebooks as I've done in the past. Well... yes and no. The Teams layer does its best
...not something ready-made, but something in continuous formation through choice of action. J. Dewey
