sgifford, would you or some mind explaining this in greater detail:

If you're printing the user's input to a Web page, you better make sure it doesn't have HTML tags in it, or else your Web site will be vulnerable to a Cross-Site Scripting attack. So, you'd better prevent code to create HTML tags, such as ><. Taint mode doesn't catch this one.

Currently, using HTML::Template, I'm doing stuff like this with data from my db: 
      my $html = "<b>Signed up:<b>\n
                 <table><tr><td>$data<\/td><\/tr>
                 <\/table>\n";
      $template  -> param(html => $html);

Cool or not?

Thanks
