 Firstly, please don't top-post. It makes it difficult to follow an email
thread.

Secondly, you can send an empty variable. For example, using the command
line tool, you would do this:

     curl -d sign-in-button= ---

Thirdly, you need to see what the "onSubmit" function does, because those
have been known to modify the contents of the form before the submit is
performed.

You should probably load LiveHTTPHeaders into Firefox and see what an actual
browser really sends to the server when you visit it.
