Correct me if I'm wrong, but there seems to be no means for an administrator to approve the enabling of a new user who has self-registered, apart from manually editing the user/accounts/user_name file "state" field. It seems that the means to do this is configurable in login plugin registration settings with "set_user_disabled: true", but there appears to be no means to actually enable the user.
Instead, with minimal changes, the only way I can see to effectively do this is to enable the send_activation_email but change the code so the activation email goes to the plugins.email.to (an administrator) address, and have "set_user_disabled: false" so that when the administrator clicks on the activation link, the user is enabled, and maybe gets a Welcome email.
This seems to me to be a bit of missing functionality.
Also, it might be staring me in the face, but there appears to be no means of setting a user's "state" via the admin console either.
Thanks,
Martin
