Add new user, role limit

Hey
I’m working on a website that runs on wordpress. I used the “User Role Editor” plugin to make a user role (named “User”) which can add posts and add users. I’d like to be able to make it so that “Users” can only add “Users” and can’t add “Editors”, “Authors”, “Contributors”, etc. Is there a plugin or file I can easily edit to do this?
Thanks
Lliam

P.s. I’m not the greatest at php coding (which is why i’m using wordpress) so can we try to keep it to as much English as possible ?? .
