Hi Nick

>can I skip send email page in guest access?

Open web/form/app/cls_ps_(tablename).inc.php and find the following lines:
//-- [BEGIN] Send email
if ( !$this->SendRegEmail( $def,
$this->fs_reg_page3,
$this->config_email
) ) break;
//-- [END] Send email
Comment them out like
//-- [BEGIN] Send email
//if ( !$this->SendRegEmail( $def,
// $this->fs_reg_page3,
// $this->config_email
//) ) break;
//-- [END] Send email

I tried but it keeps trying to mail with and error 501 Command Mail Expecting FROM:

Any help would help. Thanks

//-- [BEGIN] Send email
//if ( !$this->SendRegEmail( $def,
//	$this->fs_reg_page3,
//	$this->config_email
//) ) break;
//-- [END] Send email

I'm sure this should disable sending emails. Would you check the location one more time? Couldn't it be that you installed more than one instance of the script and edited a wrong one?
