Hi Margreth,
It sounds like adding "Pending" status for user's status is a worthy change to categorize the users who are all pending with account activation from admin. In the "User Settings" when we configure that user account creation requires approval from site administrator and when a new user registers for the site access, it shows a message to the requester that "Approval pending with site administrator and you will be notified with the approval email once approval is completed". Now the admin faces the real problem in knowing which account to be activated seeing the list of users in "User management" because both the users blocked and users with approval pending will be shown with the "Blocked" status.
We need to think of a better and feasible approach to make this status available in core "User" module and the other thing is right now they are storing the users status as Active : 1 and Blocked : 0, so if we plan to make this change available then we may need to change the way the status value is stored in the "users" table and also need to take care of the impacts of this change in other areas/ features. If anyone can comment on this that would be more helpful.
Thanks in advance :)
