        <p>Users can be edited using the below buttons once they have been selected in the table. If you need to add a group to a user(s) select it above. Once a CID user is part of a group they can be added to exams via the exam candidate page.</p>

        <h4>Create New Users</h4>
        <p>New CID users can be created by the two below buttons. If you want to create blank users you can specify the number in the associated box and click the relevant button. If you have a list of email addresses you can enter them in the relevant box and click "Add New Users From Email" and a new user will be created for each user (you do not need to specify the number of users). Ideally you will have already created a <a href="{% url 'generic:cid_group_view' %}">CID user group</a> that you can add to the newly generated users using the above select box.</p>
        <button id="add-new-cids" title="This will create N new users">Add New (Blank) Users</button>
