Thanks, but the tab doesn't show up now.

$blocklist = array_merge($blocklist, array(
    'mymodification' => array(
        'class' => 'Shelfari',
        'title' => 'My Shelfari Bookshelf',
        'hook_location' => 'profile_left_last'
    )
));

class vB_ProfileBlock_Shelfari extends vB_ProfileBlock
{
    var $template_name = 'memberinfo_block_shelfari';

    function confirm_empty_wrap()
    {
        return false;
    }

    function confirm_display()
    {
        return ($this->block_data['shelfari'] != '');
    }

    function prepare_output($id = '', $options = array())
    {
        $this->block_data['shelfari'] = '<embed width="700" height="700" src="http://www.shelfari.com/ws/shelf.swf" wmode="transparent" FlashVars="UserName=$this->profile->userinfo['field44']&ShelfType=list&verE=s1.5&ListType=isowned&booksize=large&AmazonAssociate=taljes-20&Alpha=0&BGColor=FFFFFF"></embed>';
    }
