Email в качествве имени пользоватя

Здравствуйте.

Та же проблема. Но выдает ошибку при попытке зарегистрироваться - "Заполните обязательные поля!". Хотя в файлах прописал тоже что указано тут.
Кто решил проблему с заменой логин на e-mail ?

Исправил. Кому надо, код register.php тут:

<?php

        ,'nickname' => $data['user_email']

    );

    $userdata = array_merge($data,$data2);
