How to make a submit form?

I want to make something like http://www.googlesightseeing.com/contact.php where the users can access a form and send me info. Ideally, I would like it to save the info as a draft so that I can simply publish it. mark helped me before, but I am looking for a way to do this without making the user register. Is http://www.googlesightseeing.com/contact.php a plugin or something? Thanks for reading.
