It looks fine when you use a real browser like firefox

, but to make it look good under IE go to your index.template.php file in your forums template direct and change:
/* What document type definition is being used? (for font size and other issues.)
'xhtml' for an XHTML 1.0 document type definition.
'html' for an HTML 4.01 document type definition. */
$settings['doctype'] = 'xhtml';to
/* What document type definition is being used? (for font size and other issues.)
'xhtml' for an XHTML 1.0 document type definition.
'html' for an HTML 4.01 document type definition. */
$settings['doctype'] = 'html';That should take care of it.
