Prevent creating and renaming root spaces

Help / Discuss
1

Hi.

Imagine this spaces / article structure as an example:

  • A
    • 1
    • 2
  • B
    • 3
    • 4
  • C
    • 5
    • 6
    • 7

Users should be able to edit 1-7, and to create new articles inside A, B or C. But:

  • I They shouldn’t be allowed to rename A-C.
  • II But they should be allowed to edit C.
  • III They shouldn’t be allowed to create new root spaces like D-Z.

I know how to achieve “I”. Therefor I forbid users to edit page A and B.
But to achieve “II” too I can’t forbid users to edit C. They should edit C but not rename. What can I do?
And last I don’t know how to prevent to create new spaces on root. Any suggestions?

Best would be a solution where renaming and creating root spaces could be prevented.
