Were you able to make your fields required with FrontPage? I think the only way would be with JavaScript, but then again I don't use FrontPage - maybe they have some ActiveX controls or otherwise.
I can provide some simple code... such as adding this JavaScript "onsubmit" function to your form definition:
<form name="myfrm" method="post" action="http://example.com/listmail/signup.php" onsubmit="if(!myfrm.email.value){ alert('You must enter your email address!'); return false; } if(!myfrm.fname.value){ alert('You must enter your first name!'); return false; }">
When you make changes to the next version please make it to where the
IP address and the opt-in time can be exported.
Thanks for the suggestion - yes the export process is due for an overhaul (I envision it with 'User Selection' rules and additional output options including all fields)
Regards
