(Not sure where to post this, hopefully I'm in the right forum!)
I'm looking for a way to "segregate" user creation and management in the back-end. In essence, I want to have an admin (or "super" admin) who can create editors (or "lower" admins), and assign them a group. Those editors can then create their own users within their group (subscribers only), and they can edit or delete those users, but they cannot see, edit, or delete users within any other group.
In other words, I have a website that's accessible to users only, and subscriptions are closed. The client wants to license the content of the website to other companies, creating a main login for them. They would then be able to create their own users, but shouldn't be able to see the users of any other company.
To be clear, it has nothing to do with limiting which post, page, taxonomy or tag groups (companies) would have access to. Once you're a user, you can see everything. The problem is to give "lower" admins the power to create users but limit it to some extent.
I've looked at the WP docs, forums, plugins, and can't find anything to do what I'm looking for. I realize WP wasn't really built to do that sort of thing, but I'm hoping it can be hacked into doing it somehow.
The closest thing I've found was the MemberMouse plugin, it seems to kind of being able to do what I'm looking for, but it's way, way overkill, has monthly costs, and may end up being too complicated for the client to use.
Any help you can give me would be greatly appreciated. Thanks!
