Use E-mail address instead of username for X-Cart 3.5.x & 4.0.

Let users use either their email address or username to login instead of JUST the username.

Edit include/login.php find:

$user_data = func_query_first("SELECT * FROM $sql_tbl[customers] WHERE login='$username' AND usertype='$usertype' AND status='Y'");

Change to:

$user_data=func_query_first("select * from $sql_tbl[customers] where (login='$username' or email='$username') and usertype='$usertype' and status='Y'");

Should work without troubles on 3.5.x and 4.0.x
