// check for unique email address
if (!empty($_POST['email']) AND $vboptions['requireuniqueemail'] AND $checkuser = $DB_site->query_first("SELECT username,email FROM " . TABLE_PREFIX . "user WHERE email='" . addslashes($_POST['email']) . "'"))
{
eval('$errors[50] = "' . fetch_phrase('emailtaken', PHRASETYPEID_ERROR) . '";');
}
