Making a block to show the status of the user account?
Pending User Notification Block


  This module is for sites that allow users to create an account, but
  require administrator approval for account activation. This module
  creates a block that shows a list of unactivated user accounts, with
  links to their account pages. This block is visible for anyone with
  'administer users' permission, and will not be shown to any other
  users.
