        // Check for errors in the input.

        if ( ! $in_username OR strlen($len_u) < 3  OR strlen($len_u) > 32 )

        {

            $form_errors['username'][] = $this->ipsclass->lang['reg_error_username_none'];

        }

replace with:

        // additional username checks:

        $in_usr_minlength = (int)$this->ipsclass->vars['usernames_minlength'];

        $in_usr_maxlength = (int)$this->ipsclass->vars['usernames_maxlength'];

        $in_usr_badchars  = "/[". preg_quote($this->ipsclass->vars['usernames_badchars']) ."]/";


        //echo "PATTERN: $in_usr_badchars";

        //if(preg_match($in_usr_badchars, $in_username)){

        //    echo "BAD CHARS";

        //}

        

        if (! $in_password

            OR strlen($len_p) < $in_usr_minlength

            OR strlen($len_p) > $in_usr_maxlength

            OR preg_match($in_usr_badchars, $in_username) )

        {

            $form_errors['password'][] = $this->ipsclass->lang['reg_error_no_pass'];

        }
