/**
 * Return the site-specific custom fields for the signup user form.
 *
 * To customize this for your site, copy this entire function into
 * your theme's template.php file, rename the function to
 * phptemplate_signup_user_form(), and modify to taste.  Feel free to
 * alter any elements in this section, remove them, or add any others.
 *
 * WARNING: If your site allows anonymous signups and you alter the
 * 'Name' field in this function, you will probably have to implement a
 * version of theme_signup_anonymous_username() for your site.
 *
 * In order for the form to be rendered properly and for the custom
 * fields to be fully translatable when printed in other parts of the
 * Signup module (displayed in signup lists, emails, etc), the name of
 * the form element must be $form['signup_form_data']['NameOfDataField'],
 * where NameOfDataField is replaced with the actual name of the data
 * field.  For translation to work, the displayed name of the field
 * (the '#title' property) be the same as the name of the data field,
 * but wrapped in t().  See below for examples.
 *
 * Fieldsets are not currently supported in this form.  Any
 * '#default_value' will be filled in by default when the form is
 * presented to the user.  Any field marked '#required' must be filled
 * in before the user can sign up.
 *
 * If you do not want any additional fields, the function can simply
 * return an empty array: "return array();"
 *
 * @param $node
 *   The fully loaded node object where this signup form is appearing.
 *
 * @return
 *   Array defining the form to present to the user to signup for a node.
 *
 * @see theme_signup_anonymous_username()
