Yes, this is exactly what I’m doing.
I’m using this:
https://sv.ww.wp.xz.cn/plugins/user-role-editor/
To make sure the role can only change pages that they themselves are the author of. And I can change who is the author of a page.
Now, they can still do whatever they want, basically, to that page -code-wise.
So, is that safe? Is the page a bit like a sandboxed environment?
