I am trying to create a plugin (on a fork of https://github.com/kfuchs/permission2categories) to allow the creation of questions of a category from a rank.
I saw the variable $rules ['viewable'] = 0; which allows to hide the category.
But I can't find the variable to prevent opening a new question ...
$rules ['writable'] ?
$rules ['openable'] ?
I don't know if I am precise!
