[TYPO3-english] Allowed HTML-Tags in Content Element List

[Sebastian Gebhard]

Hi,

when I create a regular List Content Element and use <b> or <i> inside, 
they will get through and final text is bold or italic.
But when I try to use <del> it will be masked by TYPO3 to &lt;del&gt;

Can I configure via TS/pageTS which tags are allowed?
