The different pages of the signup are as follows:

http://www.vispa.net/broadband-business-office500.php
http://www.vispa.net/popup-office500.html
https://secure.vispaconnect.co.uk/br...vice=office500
https://secure.vispaconnect.co.uk/broadband/y-step2.php
https://secure.vispaconnect.co.uk/broadband/y-step3.php
https://secure.vispaconnect.co.uk/broadband/y-step3.php

The last page contains the line:
<form method="POST" action="http://secure.vispaconnect.co.uk/broadband/y-step6.php">
which, I think, is what Opera baulked at.

Are you telling me that the form is sent securely?
