then i added a captcha from puremango.co.uk

join_wrap.php
[code]

    }

    $word_ok = false;
}
?>

1. in join_warp.php you have input name="family_name" and you look for $_POST['last_name'] in register.php

2. you don't set up $word = $_POST['word'] in register.php

3. you must chck if $word is OK this is first part of join_warp.php (16 lines)
