<p>To address a front end user by his name, we are using insert tags again (you might have come across them submitting a term paper). Insert tags are special tags which allow you to include dynamic data (e.g. the current date, the current user name or the current referer). Insert tags are replaced just before a page is printed to the screen, so they will always show the correct information even if the page is cached.<br><br><a rel="noopener" href="https://docs.contao.org/manual/de/artikelverwaltung/insert-tags/#body-inner" target="_blank" title="Learn more about insert tags">Learn more about insert tags</a><br><br>Below this paragraph you can see the &#34;personal data&#34; module in action. This module allows front end users to change their personal data. Make sure to cross-check all changes in the back end.</p>
