I'm setting up a site for a charity with a national branch and several sub-chapters. I'd like users of a particular chapter to be able to add/modify users, but only within their chapter's user group. It seems like with the current structure of admin permissions, I'm only able to say whether or not a user can add/edit users, and not restrict that to a particular group.
Is this possible and I'm just not seeing a setting somewhere? If not, does anyone know of a plugin that provides this functionality?
Thanks.
