<p>Selecting "No" disables the individualized invitation module. Anyone who sees or knows the URL can be interviewed. Respondents in such a case could not follow; we do not know who answered and who did not.</p>
<p>1KA system can still send (email) or document (mail, SMS, other) the sending of a general non-individualized invitation, where all respondents receive a single URL. This means that it was recorded to whom, when and how the invitation was sent, but it will not be indicated who responded and who did not.</p>
