This level of permission allows users to change the content of the board but not the structure. It is an intermediate level between "users can change everything" and "read only mode".
The structure of the board refers to the way the board is built and all the different settings regarding this board. The content refers to the content of the columns (status, due date...) as well as the different pulses.
Below is what your users will be able to do and not do with this permission level:
On the board
On the groups
On the pulses
