    $form['to'] = array(
    '#type' => 'value',
    '#value' => $account,
   );
$form['message']['subject'] = array(
'#type' => 'textfield',
'#title' => t('Subject'),
'#size' => 50,
'#maxlengh' => 255,
'#description' => t('The subject of the email message.'),
);

$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Send Mail'),
);
return $form;
}
