How to change the field label on my registration form? Drupal 7 On the default registration form, I want to change the Username label to 'Request your username'

I tried putting this in my template.php::

function mymodule_form_alter(&amp;$form, &amp;$form_state, $form_id)
{
    if ($form_id == 'user_register_form' || $form_id == 'user_profile_form') {
        $form['account']['name']['#title'] = t('Request your username');
    }
}


I cleared cache, but didn't see any changes.
Just tested on a D7 site and it should work fine for you if you name the alter function "mytheme_form_alter" instead of "mymodule_form_alter"?
