In addition, you can only edit this persons details with their approval (you may have to contact them to remind them to approve the change)
If the person is an inactive member you may have permission to edit this persons details or remove them from the list. You can also give this person a username and password so that they can become an active member of your organisation. In this way, with suitable permission who and who isn't a member of this organisation can be controlled.
