Hey,

Well I'm not sure if this is a bug or not but it seems it is since I can't find email being turned into lower cases before being inserted into the database. (I might have missed it though)

However, in this function:

/**
 * Checks to see if the email is already in use by another
 *
 * @param string The email to check.
 * @param string User ID of the user (updating only)
 * @return boolean True when in use, false when not.
 */
function email_already_in_use($email, $uid="")
{
    global $db;

    $uid_string = "";
    if($uid)
    {
        $uid_string = " AND uid != '".intval($uid)."'";
    }
    $query = $db->simple_select("users", "COUNT(email) as emails", "email = '".$db->escape_string(my_strtolower($email))."'{$uid_string}");

    if($db->fetch_field($query, "emails") > 0)
    {
        return true;
    }

    return false;
}

Souldn't email be LOWER ? I might be wrong but doesn't hurt pointing this out in case I'm not.
