Ah, sorry, you all got me confused... it's $this->template, not $this->request
<?php
class qa_html_theme extends qa_html_theme_base
{
function head_title()
{
if($this->template == 'question') {
$pagetitle=strip_tags(@$this->content['title']);
$this->output('<TITLE>'.$pagetitle.'</TITLE>');
}
else qa_html_theme_base::head_title();
}
}
