TwitterGrader: anyone with access to their API

Hi Everyone. I've been trying to get access to the Twitter grader api since weeks now. They advertise on their website that they provide access to it. I've filled the form since weeks now, done it manytime and still no answer. This is frustracting to see how most website advertise feature that they don't provide.

Anyone have access to it? Do you have any mean to contact the webmaster?

I don't want to go over their website the dirt way.
