I am on Drupal 7. When users log into a Drupal website, they aren't allowed to see the register form anymore. That is the regular behavior and I understand the reason why Drupal behaves like that.
But I have a specific situation in my website. I need users in a specific role to register new users. I will create an invisible field in my form that will tie these new users with the UserId of the "parent" user creating them. Maybe I will use the User Reference module. There is no problem here, I can do that.
The question is: how can I get the register form to be displayed to logged in users in a specific Role without giving them the "Administer users" rights? I don't trust these guys to give them that much access.
