I had thought of that and tried it but still no dice.
Basically the form looks like this:
I already have a web ID:
Web ID text field
Password Text field
I am a new customer:
So logically, if you already have an ID and pass, you fill in the top two fields and click the login button, otherwise you leave them blank, fill in the rest of the page and click the continue button at the bottom of the page.
I'm sure that's how it's supposed to work, but maybe something is broken.
