Then perhaps try this:
HTML Code:
<!-- Infobar (hack) -->
<if condition="($show['guest']) AND (THIS_SCRIPT != 'register') AND (THIS_SCRIPT != 'login')">
<div align="left" id="infobar"><a href="http://www.pirator.net/forums/register.php?"><p>It appears you have not yet registered to Pirator. To register please click here...</p></a></div>
</if>
<!-- End Infobar -->
Or, you can edit the CSS for "infobar" to align left. However, that may affect your site in other areas if that style is used in other places.
edit to add: If that DIV tag is within a TD tag, you may need to align that TD left or align the TR left. (Sorry I can't be more specific on that, I'm a Try-It-And-See type person.
